Two McGill University astronomers have assembled a “fingerprint” for Earth, which could be used to identify a planet beyond our Solar System capable of supporting…
The asteroid is likely shedding reddish dust, revealing a fresh, blue surface beneath. Last December, scientists discovered an “active” asteroid within the asteroid belt, sandwiched…

Over thirty years ago, the Infrared Astronomy Satellite discovered that the universe contained many extremely luminous galaxies, some more than a thousand times brighter than…
Study reports on search for an atmosphere around a planet somewhat similar to ours. Astronomers at MIT, Harvard University, and elsewhere have searched a rocky,…
A renegade star exploding in a distant galaxy has forced astronomers to set aside decades of research and focus on a new breed of supernova…
Jupiter’s core may still be reeling from collision 4.5 billion years ago. A colossal, head-on collision between Jupiter and a still-forming planet in the early…
A new study provides the most accurate estimate of the frequency that planets that are similar to Earth in size and in distance from their…
To understand the most ordinary matter in the universe — and the extraordinary things that happen to it — a Yale-led team of astronomers took…
In a paper published today scientists have studied the Vela Pulsar, a neutron star in the southern sky, that is 1,000 light years away. Neutron…
Lost in the glare following the Apollo 11 Moon landing, two intrepid robotic spacecraft flew by Mars in the summer of 1969 and returned photographs…
How can a planet be “hotter than hot?” The answer is when heavy metals are detected escaping from the planet’s atmosphere, instead of condensing into…
A piping hot planet discovered by NASA’s Transiting Exoplanet Survey Satellite (TESS) has pointed the way to additional worlds orbiting the same star, one of…
NASA’s newest planet hunter, the Transiting Exoplanet Survey Satellite (TESS), has discovered three new worlds — one slightly larger than Earth and two of a…
Believe it or not, this long, luminous streak, speckled with bright blisters and pockets of material, is a spiral galaxy like our Milky Way. But…
On July 23, 1999, the Space Shuttle Columbia blasted off from the Kennedy Space Center carrying the Chandra X-ray Observatory. In the two decades that…
NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered 21 planets outside our solar system and captured data on other interesting events occurring in the southern…
The Moon’s south pole region is home to some of the most extreme environments in the solar system: it’s unimaginably cold, massively cratered, and has…
