Earth-like planet breakthrough discovery

Astronomers have discovered what they say is the most Earth-like planet yet detected - a distant, rocky world that's similar in size to our own and exists in the Goldilocks zone where it's not too hot and not too cold for life.

The find excited planet hunters who have been scouring the Milky Way galaxy for years for potentially habitable places outside our solar system.

"This is the best case for a habitable planet yet found. The results are absolutely rock solid," University of California, Berkeley astronomer Geoff Marcy, said.

The planet was detected by NASA's orbiting Kepler telescope, which examines the heavens for subtle changes in brightness that indicate an orbiting planet is crossing in front of a star. From those changes, scientists can calculate a planet's size and make certain inferences about its makeup.

The newfound object, dubbed Kepler-186f, circles a red dwarf star 500 light-years from Earth in the constellation Cygnus. A light-year is almost 10 trillion kilometres.

The planet is about 10 per cent larger than Earth and may very well have liquid water - a key ingredient for life - on its surface, scientists said. That is because it resides at the outer edge of the habitable temperature zone around its star - the sweet spot where lakes, rivers or oceans can exist without freezing solid or boiling away.

The planet probably basks in an orange-red glow from its star and is most likely cooler than Earth, with an average temperature slightly above freezing, "similar to dawn or dusk on a spring day," Marcy said.

The discovery was detailed in the latest issue of the journal Science.

Lead researcher Elisa Quintana at NASA's Ames Research Center said she considers the planet to be more of an "Earth cousin" than a twin because it circles a star that is smaller and dimmer than our sun. While Earth revolves around the sun in 365 days, this planet completes an orbit of its star every 130 days.

"You have a birthday every 130 days on this planet," she said.

Scientists cannot say for certain whether it has an atmosphere, but if it does, it probably contains a lot of carbon dioxide, outside experts said.

"Don't take off your breathing mask if you ever land there," said Lisa Kaltenegger, a Harvard and Max Planck Institute astronomer.

Despite the differences, "now we can point to a star and know that there really is a planet very similar to the Earth, at least in size and temperature," Harvard scientist David Charbonneau, who was not part of the team, said.

Since its launch in 2009, Kepler has confirmed 961 planets, but only a few dozen are in the habitable zone. Most are giant gas balls like Jupiter and Saturn, and not ideal places for life. Scientists in recent years have also found planets slightly larger than Earth in the Goldilocks zone called "super Earths," but it is unclear if they are rocky.

The latest discovery is the closest in size to Earth than any other known world in the habitable region.

Kepler-186f is part of a system of five planets, all of which are roughly Earth's size. However, the other planets are too close to their star to support life.

Astronomers may never know for certain whether Kepler-186f can sustain life. The planet is too far away even for next-generation space telescopes like NASA's overbudget James Webb, set for launch in 2018, to study in detail.

Kepler completed its prime mission and was in overtime when one of the wheels that keep its gaze steady failed last year. NASA has not yet decided whether to keep using the telescope to hunt for planets on a scaled-back basis.

LADEE crashes into the dark side of the moon, avoids Apollo sites

NASA's robotic moon explorer, LADEE, is no more.

Flight controllers confirmed that the orbiting spacecraft crashed into the back side of the moon Friday as planned, avoiding the precious historic artifacts left behind by moonwalkers.

LADEE's annihilation occurred just three days after it survived a full lunar eclipse, something it was never designed to do.

Researchers believe LADEE likely vapourised when it hit because of its extreme orbiting speed of (5,800 kph), possibly smacking into a mountain or side of a crater. No debris would have been left behind.

"It's bound to make a dent," project scientist Rick Elphic predicted Thursday.

By Thursday evening, the spacecraft had been skimming the lunar surface at an incredibly low altitude of 300 feet (100 meters). Its orbit had been lowered on purpose last week to ensure a crash by Monday following an extraordinarily successful science mission.

LADEE - short for Lunar Atmosphere and Dust Environment Explorer - was launched in September from Virginia. From the outset, NASA planned to crash the spacecraft into the back side of the moon, far from the Apollo artifacts from the moonwalking days of 1969 to 1972.

Scattered over the near side of the moon: the landing portions of six lunar modules, flags, plaques, rovers and more, not to mention those memorable first footprints by Neil Armstrong and Buzz Aldrin. Apollo 12 had been projected to be closest - by several hundred miles.

The last thing the LADEE team wanted was "to plow into any of the historic sites," said project manager Butler Hine.

LADEE completed its primary 100-day science mission last month and was on overtime. The extension had LADEE flying during Tuesday morning's lunar eclipse; its instruments were not designed to endure such prolonged darkness and cold.

But the small spacecraft survived - it's about the size of a vending machine - with just a couple pressure sensors acting up.

The mood in the control center at NASA's Ames Research Center in Mountain View, California, was upbeat late Thursday afternoon, according to Hine.

"Having flown through the eclipse and survived, the team is actually feeling very good," Hine told The Associated Press in a phone interview.

But the uncertainty of the timing of LADEE's demise had the flight controllers "on edge," he said.

As it turns out, LADEE succumbed within several hours of Hine's comments. NASA announced its end early Friday morning.

It will be at least a day or two before NASA knows precisely where the spacecraft ended up; the data cutoff indicates it smashed into the far side of the moon, although just barely.

LADEE did not have enough fuel to remain in lunar orbit much beyond the end of its mission. It joined dozens if not scores of science satellites and Apollo program spacecraft parts that have slammed into the moon's surface, on purpose, over the decades, officials said. Until LADEE, the most recent man-made impacts were the LCROSS crater-observing satellite that went down in 2009 and the twin Grail spacecraft in 2012.

During its $280 million mission, LADEE identified various components of the thin lunar atmosphere - neon, magnesium and titanium, among others - and studied the dusty veil surrounding the moon, created by all the surface particles kicked up by impacting micrometeorites.

"LADEE's science cup really overfloweth," Elphic said earlier this month. "LADEE, by going to the moon, has actually allowed us to visit other worlds with similar tenuous atmospheres and dusty environments."

Our sun's long-lost stellar sibling found at last, astronomers say
Image


A star born from the same cloud of gas as our sun 4.5 billion years ago has been found at last, astronomers say.

This solar sibling is a little bigger than our sun, and a little hotter at its surface. But an international team of researchers says it has the same chemical fingerprint as the star at the center of our solar system, leading them to conclude both stars were born in the same stellar nursery, at the same time.

Me dad spotted a burning Nova in the constellation Hercules back in '36. He ground his own lens and used a water softener canister as the capture scope/tube. To adjust for any movement, he drilled a hole and filled it with cement that still stands in a parking lot today. A testament to my Pops tenacity!
He reported it to the authorities at the Greenwich Labs in England to confirm. They did and NBC flew him up to NYC from Columbia, SC to be on NBC radio. ( big doin's at the time) I've got a nice 8X10 of him talking into an NBC mic. Small town boy make big time, is how all the papers played it up. He only told me about it when we we're high in the Sierra's pointing out where, why and how (in his opinion) all this that we enjoy was made*. He, and I guess I am now, a John Muir kinda' pupil of life. Look up, look down, but learn and enjoy it all and above all, learn from your observations.
That pretty simple. Space isn't deep, unless you want it to be,.... then it's there, deep as can be!

*That Nova has made a new sun and we say it's the closest to our own. How presumptuous! There's a lot more out there. Me Pops and I know it. :wink:

Meteor shower will be dazzling - for some

Some astronomers have high hopes that a meteor shower the Earth will pass through for the first time tomorrow could be particularly active.

Some forecasters have predicted there might be more than 200 meteors an hour, but they will not be visible from New Zealand.

The shower will be caused by dust from a relatively dim comet known as 209P/LINEAR, which was discovered in 2004 and dips inside the Earth's orbit once every five years.

The National Aeronautics and Space Administration (Nasa) said the Earth would tomorrow pass through streams of dust ejected by the comet more than a century ago.

No-one was sure how much debris was waiting. It depended on how active the comet was when the debris stream was laid down.

"We have no idea what the comet was doing in the 1800s," Nasa Meteoroid Environment Office head Bill Cooke said.

"There could be a great meteor shower or a complete dud."

The most likely time for the Earth to cross paths with the debris was between 6pm and 8pm (NZ time) tomorrow.

Some parts of North America will get a good view.

"It's really badly placed for us to observe in New Zealand. We're very unlikely to see anything," Carter Observatory astronomer Claire Bretherton said.

The radiant - the point in the sky where the meteors would appear to be coming from - was in the northern hemisphere, close to the North Star.

"That part of the sky is about as far away from visible here as it is possible to get," she said.

The meteor shower is called the May Camelopardalids. That is because meteor showers are named for the constellation from which they seem to radiate, which in this case will be Camelopardalis, which means camel leopard, the Roman description of giraffes.

Most meteor showers occur when the Earth orbits through a trail of dust shed by a comet as it makes its own way around the Sun.

That dust burns up in our atmosphere and causes what looks like shooting stars to streak across the sky.

Astronomers discover new planet 'mega-Earth'

Astronomers have discovered a new type of rocky planet beyond the solar system that weighs more than 17 times as much as Earth while being just over twice the size, scientists said on Monday.

The so-called ‘‘mega-Earth’’ circles a very old star called Kepler-10, which is located about 560 light-years away from Earth in the constellation Draco.

The discovery, announced at the American Astronomical Society meeting in Boston, was a surprise since planets that big were believed to be mostly gas, not solid rocky bodies like Earth or Mars, said physicist Dimitar Sasselov, director of the Harvard Origins of Life Initiative.

Scientists do not yet understand how the planet, known as Kepler-10c, formed. It has a diameter of about 18,000 miles (29,000 km), 2.3 times greater than Earth’s.

‘‘A mega-Earth is a lot of solids concentrated in the same place without any gas. That is a problem because our understanding for how planets form requires the solids to get together in an environment where almost 99 percent of the mass ... is hydrogen and helium,’’ Sasselov told reporters at a press conference.

Smaller solid bodies, like Earth or Mars, which are believed to form from leftover materials, take less time to pull themselves together. With a longer incubation time, large planets should gather up massive amounts of gas in the process — or so scientists thought.

However, mega-Earths formed, the discovery of another type of rocky world bodes well in the search for life beyond Earth, Sasselov added.

‘‘As far as we know — and we know very little about origins of life — we think the emergence of life from geochemistry,’’ occurs on solid planets, Sasselov said.

Related research shows that about 75 percent of the planets found with NASA’s Kepler space telescope are less than four times Earth’s diameter.

In the solar system, there is nothing between the size of Earth, the largest rocky planet, and Neptune, the smallest gas giant with a diameter nearly four times Earth’s.

‘‘We really want to know about these planets,’’ astronomer Lars Buchhave, with the Harvard-Smithsonian Center for Astrophysics, told reporters.

‘‘Are they rocky planets with a thin, compact atmosphere like the Earth, or are they rocky cores with some sort of extended hydrogen-helium envelope and where there is really no surface?’’ he said.

This is a pretty cool video (total time: 49 seconds), taken over four years by the Hubble Telescope. It shows a variable star known as V838 Monocerotis, which has just blown off its outer shell. It's not a supernova, and probably doesn't even qualify as a nova, but it's worth the minute it takes to watch it...

You may recognize that picture. It was used - in somewhat Photoshopped form - in the opening sequence of the recent remake of "Cosmos."

It was also used in the Lord Of The Rings movies as part of the Eye Of Sauron:

'Magic Islands' Appear On Saturn's Moon Titan

Image

Scientists have struggled to explain how a 'magic' island appeared in the middle of a lake on Saturn's moon Titan - and then disappeared.

Titan is one of the largest Moons in our solar system, and the biggest orbiting the ringed planet.

It is of particular interest to astronomers because it has both a thick atmosphere, a rocky surface and surface liquid lakes. While the lakes are made of methane and ethane, rather than water, they are able to exist as liquid at temperatures lower than 180C and make it unique among known worlds other than our own.

Various proposals for exploring Titan have been made in recent months and weeks, including a mothership and drone team, and even a submarine.

But the depth of our ignorance surrounding Titan was made even more clear on a recent fly-past of the space probe Cassini-Huygens.

On the flyby of the Moon in 10 July 2013, Cassini spotted a new island in the middle of Ligeia Mare, the second-largest lake on the world.

But when the craft made its next pass around the planet it had vanished.

Scientists have proposed various explanations in a new paper published in Nature Geoscience, but say its appearance is still largely unexplained.

Among the potential solutions are that the 'island' was a giant wave, a bubble of gas, a floating 'solid' island or a 'suspended solid'.

Scientists think the island -- whatever it is -- was caused by the seasons which extrapolate on the Moon over the course of 30 years.

During the 'summer' on Titan (which is about to start) winds get stronger because more of the Sun's energy is directed at the northern hemisphere. That also leads to larger waves, which might be why the island appeared. It might also lead to the melting of icebergs made of methane and ethane.

Debunked! No fairytale ending for Goldilocks planet
SANDHYA SOMASHEKHAR

The discovery four years ago of a rocky, not-too-distant planet that seemed a prime candidate for alien life was a thrilling development in the search for other Earths - proof, it seemed, that our planet was not the only one with just the right mix of life-sustaining conditions.

But two scientists at Penn State University say they have debunked the possibility of a "Goldilocks" planet once believed to revolve around Gliese 581, a faint dwarf star that is 20 light-years from Earth.

Using a new technique they are developing to confirm the existence of small, hard-to-detect planets, the researchers say they have determined that physical changes within the star itself created the illusion of an orbiting Goldilocks planet and a second one that also does not exist.

Three other planets do exist, they said, in the Gliese 581 planetary system, but none within the star's "habitable zone" - an area just the right distance from the star to allow the presence of liquid water.

"It's bittersweet," said Suvrath Mahadevan, one of the researchers who conducted the study, published on Thursday afternoon (local time) in the journal Science. "We are pleased the technique works, but on the other hand, we have disproved these two planets. It would have been nice if they had existed."

Steven Vogt of the UCO/Lick Observatory at the University of California at Santa Cruz, one of the astronomers who first reported the existence of the "Goldilocks" planet, did not respond to emails this week. Paul Butler of the Carnegie Institution of Washington, his co-researcher, declined to comment for this story.

This is not the first time the planet's existence has been questioned.

Vogt and Butler reported their initial discovery in the Astrophysical Journal in September 2010, reporting that they had found, for the first time, something long predicted by astronomers: a planet, orbiting a distant star, with the right balance of temperature and mass to host liquid water and an atmosphere - two conditions presumably necessary to support life as we know it.

The planet, Gliese 581G, was about three or four times the mass of Earth, they said. Unlike Earth, which rotates on its axis, Gliese 581G was fixed in relation to its sun, with only one side perpetually bathed in light, they said. The most likely area for life, they said, was in a band around the planet where the dark side met the illuminated one.

"The logic now says there are lots of planets like this out there," Vogt told The Washington Post at the time. In later interviews, he said he believed that the planet probably hosted alien life.

Since then, however, a number of astronomers have cast doubt on the existence of Gliese 581G. A Swiss team reported that it was unable to find evidence of the planet. Vogt and Butler published a follow-up paper defending their research.

"We stand by our data and results and are hard at work obtaining more of our own data on this system," Vogt told Space.com in February 2011.

The Penn State researchers used a different measure of the star's activity to reach their conclusions. Using their new technique to process existing data, they said, they were able to correct for activity on the star's surface — a sun spot, for example — that could be misinterpreted as evidence of a planet around the star. In the new analysis, evidence that the three true planets in the system exist was strengthened, while the suspect planets disappeared, they said.

Paul Robertson, the lead researcher on the new paper, said his intent was not to critique Vogt and Butler's methods but to provide a new tool for scientists hunting for new planets.

"I think the astronomers did more than due diligence," he said of Butler, Vogt and other researchers who have looked at this system. "I think their work is more than defensible, it's perfectly good science, and all those groups continue to do good science. This is the scientific method. You have this happen all the time, where you have a result that looks to all the world correct, but if you introduce a new perspective or a new tool, those results can change."

Since Butler and Vogt's initial report, scientists have found 22 other potentially habitable planets outside Earth's solar system, according to the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo, which keeps a catalogue of "exoplanets," or planets outside Earth's solar system. Dozens of others are awaiting confirmation that they exist and are habitable.

In astronomy circles, where there was already widespread skepticism about the existence of the 'Goldilocks' planet, the bigger news from Thursday's report was the debunking of Gliese 581D, a massive "super-Earth" thought to have a dense, murky atmosphere. Its purported discovery in 2007 by French scientists was a bombshell because it was so different from Earth — and yet still could have harboured life.

"It would be extremely disappointing if one of our favorite exoplanets...actually does not exist," said Sara Seager, a professor of planetary science and physics at the Massachusetts Institute of Technology. It is "one of our favorite planets because it motivated people to seriously consider planets more massive than Earth as potentially habitable."

Edwin "Buzz" Aldrin walked on the Moon forty-five years and one day ago. Yet every once in a while he gets confronted by some asshole who refuses to accept that he really did walk on the Moon.

Word to the wise: Buzz Aldrin's patience has limits...
