One black hole or two? Dust clouds can explain puzzling features of active galactic nuclei
Researchers at the University of California, Santa Cruz (UCSC), believe clouds of dust, rather than twin black holes, can explain the features found in active galactic nuclei (AGNs).... full story »

Possible Subsurface Lake near Martian South Pole
A new paper published in Science this week suggests that liquid water may be sitting under a layer of ice at Mars' south pole.... full story »

A cosmic quirk helps astronomers pinpoint the farthest star ever seen
More than halfway across the universe, an enormous blue star nicknamed Icarus is the farthest individual star ever seen. Normally, it would be much too faint to view, even with the world’s largest telescopes.... full story »

Astronomers See Distant Eruption as Black Hole Destroys Star
For the first time, astronomers have directly imaged the formation and expansion of a fast-moving jet of material ejected when the powerful gravity of a supermassive black hole ripped apart a star that wandered too close to the massive monster.... full story »

Juno Solves 39-Year Old Mystery of Jupiter Lightning
In a new paper published in Nature today, scientists from NASA's Juno mission describe the ways in which lightning on Jupiter is actually analogous to Earth's lightning. Although, in some ways, the two types of lightning are polar opposites.... full story »

NASA Finds Ancient Organic Material, Mysterious Methane on Mars
NASA's Curiosity rover has found new evidence preserved in rocks on Mars that suggests the planet could have supported ancient life.... full story »

Earth's magnetic field simpler than we thought
Scientists have identified patterns in Earth's magnetic field that evolve on the order of 1,000 years, providing new insight into how the field works and adding a measure of predictability to changes in the field not previously known.... full story »

Shocking case of indigestion in supermassive black hole
A multi-wavelength study of a pair of colliding galaxies has revealed the cause of a supermassive black hole's case of 'indigestion'.... full story »

NASA's Kepler Mission Announces Largest Collection of Planets Ever Discovered
NASA's Kepler mission has verified 1,284 new planets -- the single largest finding of planets to date. This gives us hope that somewhere out there, around a star much like ours, we can eventually discover another Earth.... full story »

NASA mission reveals speed of solar wind stripping Martian atmosphere
NASA has identified the process that has played a key role in the transition of the Martian climate from an early, warm and wet environment to the cold, arid planet Mars is today.... full story »

2012: Fear No Supernova
Given the incredible amounts of energy in a supernova explosion -- as much as the sun creates during its entire lifetime -- another erroneous doomsday theory is that such an explosion could happen in 2012 and harm life on Earth.... full story »

Astronomers Discover Deep-Fried Planets: Two Earth-Sized Planets Around Dying Star That Has Passed the Red Giant Stage
Two Earth-sized planets have been discovered around a dying star that has passed the red giant stage. ... full story »

Astronomers Discover Rare Galaxy at Dawn of Time
Astronomers, including the University of California, Riverside's Bahram Mobasher and his graduate student Hooshang Nayyeri, have discovered that one of the most distant galaxies known is churning out stars at a shockingly high rate.... full story »

Detecting the 'Heartbeat' of Smallest Black Hole Candidate
An international team of astronomers has identified a candidate for the smallest-known black hole using data from NASA's Rossi X-ray Timing Explorer (RXTE). ... full story »

Young Star Rebels Against Its Parent Cloud
Hubble's Wide Field Camera 3 has captured this image of a giant cloud of hydrogen gas illuminated by a bright young star. The image shows how violent the end stages of the star-formation process can be, with the young object shaking up its stellar nursery.... full story »
