Not enough hours in the day? At least you're not on planet Beta Pictoris b

By - May 4, 2014 9 Pictures
According to NASA, 1,703 planets orbiting 1,033 stars have been found so far, but very little is known about these planets beyond some deductions based on their orbits. That veil is lifting though, as demonstrated by Dutch astronomers who have for the first time measured the length of an exoplanet’s day. Using the European Southern Observatory’s Very Large Telescope (VLT) in Chile’s Atacama desert, the team has learned that the young extrasolar gas giant Beta Pictoris b has an eight-hour day and spins faster than any planet in the Solar System.

Kepler discovers most potentially habitable planet yet

By - April 17, 2014 4 Pictures
The search for extraterrestrial life zeroed in a bit today as NASA announced that its unmanned Kepler Space Telescope detected the most Earth-like planet yet found beyond the Solar System. Named Kepler-186f, the new planet orbits a red dwarf star about 500 light years away from Earth in the constellation of Cygnus, is only 10 percent larger than our planet, and could have liquid water, which is essential for life as we know it.

JPL develops space flowers to help find Earth-like planets

By - March 25, 2014 9 Pictures
Apparently NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, thinks that what space exploration in the 21st century needs is spacecraft that are a bit more botanical. The center has released a video showing off its starshade spacecraft that opens up like a blossom. Bearing a resemblance to a cosmic sunflower, it’s designed to help astronomers to directly study exoplanets, including taking the first actual pictures of planets beyond our Solar System. Read More

Kepler strikes exoplanet mother lode, 715 new planets discovered

By - February 27, 2014 7 Pictures
It’s a good thing that planets outside our Solar System get catalog designations instead of proper names, or space scientists would now be scraping the barrel for “Ralph” or “Tigger.” That’s because on Wednesday, NASA announced that the Kepler space telescope had hit the “motherload” of exoplanets, confirming 715 new planets in 315 star systems. It used a new statistical technique that the space agency says has removed a bottleneck that has plagued the analysis of the Kepler data. Read More

Kepler demonstrates that it can still detect planets

By - February 19, 2014 4 Pictures
Last year, it looked as though the Kepler space probe had nothing to look forward to but the scrap heap. After the failure of two of its reaction wheels, the unmanned spacecraft was incapable of maintaining the precision pointing needed to hunt planets beyond the Solar System. Now, however, NASA’s Kepler team has demonstrated that space telescope can still detect exoplanets thanks the K2 mission concept maneuver. Read More

Alpha Centauri B may have "superhabitable" worlds

By - January 27, 2014 10 Pictures
Since Earth is the only known inhabited planet and we happen to live here, it’s only natural to regard it as the ideal place for life to exist, and to assume that another life-bearing planet would be fairly similar. However, that is not the opinion of scientists René Heller and John Armstrong who contend that there might be a planet even more suitable for life than Earth 4.3 light years away orbiting the star Alpha Centauri B.

Gemini Planet Imager snaps first direct image of exoplanet Beta Pictoris b

By - January 9, 2014 7 Pictures
Following almost 10 years of development, the Gemini Observatory has debuted an advanced planet imaging instrument and captured a direct image of exoplanet Beta Pictoris b, signifying a breakthrough in our ability to analyze extrasolar planets. Called the Gemini Planet Imager (GPI), the tool uses an advanced optics system with an infrared spectograph to retrieve direct images of young planets orbiting distant stars. Read More

Astronomers say one in five sun-like stars likely to have habitable planets

By - November 5, 2013 7 Pictures
Bookmakers may be revising their odds on the question of us being alone in the Universe after scientists revealed that our galaxy could hold billions of habitable worlds. University of California Berkeley and University of Hawaii (UH) astronomers carried out a study using data from NASA’s Kepler space telescope to provide part of the answer to the question, “How many of the 200 billion stars in our galaxy have potentially habitable planets?” The answer they got back was that one in five sun-like stars may have Earth-size planets that could support life.
