Scientists Spot Distant Planet With Comet-Like Tail

Astronomers using the Hubble space telescope have spied a distant, Neptune-sized planet throwing off a massive cloud of hydrogen gas that makes it look something like a super-comet in close orbit around its red dwarf star, Gliese 436.

X-rays firing off of the star are burning off the upper atmosphere of its exoplanet, GJ 436b, creating the gaseous cloud that then absorbs the light of the star, reflecting ultraviolet rays that are visible from Hubble.

Rare system of five stars discovered

The quintuplet consists of a pair of closely linked stars - binaries - one of which has a lone companion; it is the first known system of its kind.

The pair of stars orbit around a mutual centre of gravity, but are separated by more than the distance of Pluto's orbit around the Sun.

The findings have been presented at the UK National Astronomy Meeting in Llandudno.

The unusual system lies 250 light-years away in the constellation Ursa Major. It was discovered in data gathered by the SuperWASP (Wide Angle Search for Planets) project.

This uses relatively small and low-cost cameras in the Canary Islands and South Africa to image much of the sky every few minutes.

The exoplanets that hint at life billions of years older than Earth: Five new planets raises possibility of super-advanced civilisations

A solar system including five Earth-sized planets has been discovered which is so ancient it was born not long after the dawn of time - and experts say it could help find life on planets far older than we expected.

The system's parent star, named Kepler-444, is 117 light years from Earth and 11.2 billion years old.

When the sun-like star was formed out of a primordial cloud of gas and dust, the universe was just a fifth of its current age.

Jupiter twin discovered around solar twin

Astronomers have used the ESO 3.6-metre telescope to identify a planet just like Jupiter orbiting at the same distance from a Sun-like star, HIP 11915. According to current theories, the formation of Jupiter-mass planets plays an important role in shaping the architecture of planetary systems. The existence of a Jupiter-mass planet in a Jupiter-like orbit around a Sun-like star opens the possibility that the system of planets may be similar to our own Solar System.

So far, exoplanet surveys have been most sensitive to planetary systems that are populated in their inner regions by massive planets, down to a few times the mass of the Earth. This contrasts with our Solar System, where there are small rocky planets in the inner regions and gas giants like Jupiter farther out.

so, 1st radio transmission was 1894...121y ago!

they r 117ly away...if they had warp3 capability, they would be here by 2/3y ago!
if they have wapr2 capability, they will arrive in 8y from NOW!
:D :P

'Another Earth?': NASA hints at planetary discovery

NASA is teasing space enthusiasts, hinting that it may have some big news to announce about other Earth-like planets in the Milky Way.

The space agency said it plans to share a new discovery from its Kepler Space Telescope at a news conference scheduled for 9 a.m. PDT on Thursday.

The Kepler mission, launched in 2009, is dedicated to finding Earth-like planets in what scientists call the "habitable zone," or the region near stars where orbiting planets might have the conditions to support the existence of liquid water.

'Earth 2.0' found in Nasa Kepler telescope haul

A haul of planets from Nasa's Kepler telescope includes a world sharing many characteristics with Earth.

Kepler-452b orbits at a very similar distance from its star, though its radius is 60% larger.

Nasa scientists said they believe it is the most Earth-like planet yet.

Such worlds are of interest to astronomers because they might be small and cool enough to host liquid water on their surface - and might therefore be hospitable to life.

Nasa's science chief John Grunsfeld called the new world the "closest so far" to Earth.

"It's a real privilege to deliver this news to you today," said John Jenkins, Kepler data analysis lead at Nasa's Ames Research Center in California.

"There's a new kid on the block that's just moved in next door."

http://www.bbc.com/news/science-environment-33641648

I wouldn't say that Kepler 452b is on our block unless you consider anywhere in the Milky way qualifies. At 1,400 ly we aren't going there any time soon.

Brown Dwarf.

Astronomers find aurora a million times brighter than the northern lights

The sky above a failed star in a distant constellation shimmers with a beautiful green and yellow aurora one million times brighter than the northern lights. The spectacular light show is the first confirmed aurora on a body outside the solar system, and the most powerful ever recorded.

Astronomers detected the celestial display when they trained some of the world’s most sensitive telescopes on a brown dwarf that lies 18 light years away in the constellation of Lyra. The aurora’s colourful streaks wave green and yellow when oxygen and sodium are battered by electrons in the brown dwarf’s atmosphere. The brightest light the telescopes picked up was from hydrogen, which glow redder than the eye can see.

NASA's Spitzer Confirms Closest Rocky Exoplanet

Using NASA's Spitzer Space Telescope, astronomers have confirmed the discovery of the nearest rocky planet outside our solar system, larger than Earth and a potential gold mine of science data.

Dubbed HD 219134b, this exoplanet, which orbits too close to its star to sustain life, is a mere 21 light-years away. While the planet itself can't be seen directly, even by telescopes, the star it orbits is visible to the naked eye in dark skies in the Cassiopeia constellation, near the North Star.

HD 219134b is also the closest exoplanet to Earth to be detected transiting, or crossing in front of, its star and, therefore, perfect for extensive research.

& they didn't say how OLD is the system!!!

why?
if it's an older system then ours, then it should be listed HIGH on next SETi candidates search with directed telescopes... ;)

then it should be listed HIGH on next SETi candidates

It is not in the habitable zone in regards to temperature.

This press release suggests that there are no habitable planets within this distance from Earth (18 light years).

Searching for other habitable planets. Up next is an interesting article.


Searching for a ‘superhabitable’ planet in Alpha Centauri

Throughout 2014, the overlapped trajectories of the two main stars of Alpha Centauri prevented us from observing them. As they’ve begun to separate, scientists have been able to begin searching our nearest stellar neighbor for any sign of a potentially superhabitable planet (a planet more habitable than Earth itself).

http://www.extremetech.com/extreme/211820-the-search-for-a-superhabitable-planet-in-alpha-centauri-b-resumes

All very speculative. Here "Super Earth" refers to a planet bigger than Earth. I don't know if we have found and verified a rocky planet in the habitable zone at all.

I would like to see the list of requirements for a habitable planet to evolve intelligent life.

You have to assume an ET species exists at a concurrent level of technology to ours. There is a possibility that ET's may exist at a level of development 100 years in our past or earlier or 150 years in our future or further ahead in time than that. Either postulated ET species would likely not be detected by us as in the first species Radio TX/RX does not yet exist and in the second the ET Species may gave moved beyond RF wave propagation to something as yet unknown to us or only understood at most basic level. Thus the second species we would be blind to as well. Thus time coincidence in technological development is a crucial element for the search.

For some reason we Earthbound species think that all species are maturing in time coincidence to us... Perhaps its a subtle religious thing.. Yet an ET Civilization able to travel through the vast distances between stars likely is technologically superior to us to include communication methodology and techniques. Likely we would not recognize a "signal" if it employed methods like Quantum entanglement, or Neutrino emissions etc... In order for us to have an appropriate intercept receiver we would need to understand the technology and therin lies the difficulty. We just don't know enough.. Even subtle modulation techniques employed today are quite invisible to 98% of the receivers out there. SETI needs to be highly skilled in receiver and modulation technology.

And then there is the dwell issue. The longer your antenna is able to stare at or dwell on a given source point the more likely it is that you may intercept. SETI has utilized principally AERICIBO RT data. By design this aperature sweeps the sky in swaths and has only limited time to dwell or stare a point source before the earths rotation moves the scan past and away. Thus we are examining only short exposures to signal sources, in a limited band, for a miniscule period and likely not repeated for months or year on end.. All of the above factors delimits the current SETI efforts of the at home examination to less than optimal chance for success.

Recent efforts use pointing RT's at confirmed lucrative target sets all will change that success probability... We are entering into an exciting time..

Never engage stupid people at their level, they then have the home court advantage.....

then it should be listed HIGH on next SETi candidates

It is not in the habitable zone in regards to temperature.

yeah it is in habitable zone...otherwise it wouldn't be called "Earth 2.0"!

also, there r other candidates:


Q is: has SETi checked all those candidates 4 signals?

They found another Jupiter. They need to find exoplanets with oxygen.

Astronomers discover 'young Jupiter' exoplanet

Athens, Ga. - A team of astronomers that includes University of Georgia professor Inseok Song has discovered a Jupiter-like planet within a young star system that could serve as a decoder ring for understanding how planets formed around the sun.

The new planet, called 51 Eridani b, is the first exoplanet discovered by the Gemini Planet Imager, a new instrument operated by an international collaboration headed by Bruce Macintosh, a professor of physics in the Kavli Institute at Stanford University. It is the faintest exoplanet on record and also shows the strongest methane signature ever detected on an alien planet, which should yield additional clues as to how the planet formed.
