Kepler-10c is 17 times more massive than the Earth (Image: NASA/Harvard-Smithsonian Center...

Despite being currently offline, the Kepler space telescope is still turning up surprises. One of them is an Earth-like planet that’s so large that astronomers at the Harvard-Smithsonian Center for Astrophysics call it a “mega-Earth.” Planet Kepler-10c is 17 times heavier than the Earth, and may require scientists to rethink their ideas on planet formation and the likelihood of life in our galaxy.  Read More

Jupiter's Great Red Spot has been a source of inspiration and curiosity for generations of...

Data collected by NASA's Hubble Space Telescope over the past 20 years show Jupiter's Great Red Spot has been shrinking at an increasing rate to its current, and smallest, recorded size. The reduction is possibly due to the existence of eddies, that have been observed feeding into the planet-sized storm.  Read More

Recent data captured by NASA's Chandra Observatory and Spitzer Space Telescope has cast doubt on the basic model that accounts for the creation of star clusters. The data, collected from studies of NGC 2024, located in the Flame Nebula and the Orion Nebula Cluster, will require scientists to think up an entirely new approach as to how these celestial bodies come into creation.  Read More

WISE J085510.83-071442.5.0 is the coldest brown dwarf yet found (Image: NASA)

We tend to think of stars as being very, very hot, but what about a star that you could use as a deep freeze? Astronomers using NASA's Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescope have discovered a dim star-like object with the catchy title WISE J085510.83-071442.5.0 that is colder than the North Pole. Lying about 7.2 light years from Earth, it is not only the coldest brown dwarf on record, but the fourth-closest star system to the Solar System.  Read More

Artist's impression of Kepler-186f (Image: NASA)

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.  Read More

The 20-gigapixel panorama is compiled from more than 2 million individual snaps (Image: NA...

Images from the NASA Spitzer Space Telescope have been used to create a staggering 20-gigapixel panorama, encompassing more than half of the galaxy’s stars. The vista was created from more than a decade’s worth of infrared images, and will be used to help further our understanding of the structure and formation of stars in the Milky Way.  Read More

Starshade and its space telescope (Image: NASA)

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 has produced results needed to take the next big step forward in humankind's searc...

It’s been five years since NASA’s $600 million Kepler Space Telescope was launched to look for planets beyond our Solar System – so-called exoplanets – and while the quest to find a twin for Earth has so far been fruitless, Kepler’s observations have revealed our galaxy to be full of worlds potentially able to support life.  Read More

Artist's concept of exoplanet systems (Image: NASA)

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

The newly detected radioactive elements of Cas A glow blue in this composite image (Image:...

NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) is unraveling the mystery of how stars go supernova by mapping the remnants of radioactive material left in the wake of a supernova. The findings go against previous theories to create a more chaotic view of the conditions prevailing directly before a star explodes.  Read More
