HD 209458b: Is it a comet or a planet?

How about a planet that acts like a comet! The Hubble Space Telescope has found planet HD 209458b. NASA says it is a gas giant that is so close to its star'”about 4 million miles away'”that its atmosphere is escaping into space so fast that the created winds look like a sweeping tail of a comet.

Astronomers see first super-wind on exoplanet

In a first-ever discovery, astronomers have detected fierce, supersonic winds on a planet outside of our own Solar System, what is called an extrasolar planet, or exoplanet. In this case, winds of up to 6,200 miles per hour are blowing on the exoplanet HD 209458 b.

First orbit of exoplanet directly observed

Astronomers have directly tracked the orbit of an extrasolar planet (exoplanet) for the first time. And, the star about which the exoplanet, Beta Pictoris b, is orbiting is the youngest star known to parent a planet.

Gold mine of an exoplanet: Corot-9b

Astronomers are studying a planet called Corot-9b, which is about 1,500 light years from Earth, that they say will be studied in great detail because it is very similar to our planets in the Solar System. They think it might be reveal a "gold mine" of information.

 

Published in Space
NASA astronomer Brian Jackson has presented information that the exosolar planet Corot-7b is vaporating due to its decreasing distance to its parent star. Its molten surface is so hot that the planet is slowly evaporating due to extreme temperatures of upwards of 1,980 degrees Celsius (3,600 degree Fahrenheit).

Five new exoplanets found by Kepler telescope

The Kepler Space Telescope has discovered five new planets and they are being called Kepler 4b, 5b, 6b, 7b, and 8b.

Published in Space
Five Earth-like planets (and maybe two additional ones) orbiting Sun-like stars have been discovered (and announced in and around December 14, 2009) by an international team of astronomers lead by an Australian and American. Such discoveries add to the eventual hope (and maybe even expectation) that scientists will discover life on one of them.

Published in Space
European astronomers have announced that 32 exoplanets have just been discovered using instruments at the European Southern Observatory, taking the number of planets orbiting around stars other than the Sun to over 400.

Published in Space
Astronomers have found over 300 exosolar planets (or exoplanets, those orbiting about stars other than the Sun). However, they have all been gaseous objects without a solid surface. For the first time, a rocky exoplanet has been discovered.

Published in Space
The Kepler Mission to find exosolar planets is just out of the starting gate, and it has already verified that it is up to the challenge of finding exoplanets (those that orbit stars other than the Sun) about the size of Earth. Kepler is the Exoplanet-Hunter!

Swiss planet finders find smallest one so far

Swiss astronomers announced on April 21, 2009, that they found planet Gliese 581 e, the least massive planet ever found outside of our Solar System. It is just less than double the mass of Earth. They like their planets small, like Earth, because it increases the possibility of finding life.

Exoplanet mission launched: Kepler to space

The Kepler Mission was successfully launched into space from the Cape Canaveral Air Force Station at 10:49 p.m. Eastern Standard Time on Friday, March 6, 2009. The NASA mission is to find the first habitable planets the size of Earth orbiting about stars in the constellations Cygnus and Lyra.

The Kepler spacecraft and its Delta II rocket are ready to lift off from Launch Complex 17-B at the Cape Canaveral Air Force Station. Scheduled lift off is 10:49 p.m. EST on Friday, March 9, 2009. Its mission is to answer the question: Are planets out there like Earth?

Huge discovery of tiniest exoplanet

A French-led astronomy team found the smallest exolanet ever discovered directly. Even though it is just over 11 times the size of Earth, it could be a gigantic discovery in the world of extrasolar planets, or exoplanets.

Published in Space
NASA announced on Thursday, February 26, 2009, that its Kepler Space Telescope will launch no earlier than Friday, March 6, one day later than originally scheduled, to double-check common hardware carried by Kepler’s rocket and the Taurus XL rocket that carried the Orbiting Carbon Observatory, which crashed after its launch.

According to Dr. Alan Boss, our Milky Way galaxy could contain one hundred billion Earth-like planets. However, he says very few of these planets would be able to support intelligent life. But, what about primitive (microscopic) life?

Published in Space
As astronomers expand their search with the Kepler Space Telescope for Earth-like planets outside of our Solar System, they are also seriously expanding their search for life on these extraterrestrial worlds. Shouldn’t we also come up with more serious names for these life forms that we will most likely find?

Hubble is a carbon dioxide planet finder

NASA announced on 12.9.2008 that its extraordinary Hubble Space Telescope (HST)  discovered the chemical compound carbon dioxide in the atmosphere of a planet orbiting a Jupiter-sized star called HD 189733b. This discovery is important in the continuing search for life on other planets in the Universe.

Published in Space
For the first time, astronomers have directly observed a planet orbiting a star other than our own Sun. The historic image was captured by the Hubble Space Telescope.

Published in Space
Canadian astronomers have discovered and photographed for the first time what they think is a normal sized exosolar planet (exoplanet) orbiting a star other than the Sun. However, if true it could change our theories of planet formation.
