Planets forming in Pleiades star cluster, astronomers report
Rocky terrestrial planets, perhaps like Earth, Mars or Venus, appear to be forming or to have recently formed around a star in the Pleiades ("seven sisters") star cluster, the result of "monster collisions" of planets or planetary embryos. view more (2007-11-16)
Catching a Glimpse of a Black Hole's Fury
Using the National Science Foundation's (NSF) Very Long Baseline Array (VLBA) and a host of international telescope partners, a team of researchers has made the clearest observation yet of innermost region of a black hole. view more (2008-04-24)
Neutron stars warp space-time, U-M astronomers observe
Einstein's predicted distortion of space-time occurs around neutron stars, University of Michigan astronomers and others have observed. view more (2007-08-29)
Discovery confirms explosive prediction made by astrophysicists in 1999
NASA's Swift satellite and ground-based telescopes have discovered the most distant exploding star on record, confirming a 1999 prediction made by University of Chicago astrophysicist Don Lamb and Daniel Reichart, who was then a graduate student at Chicago. view more (2005-09-13)
Three new 'Trojan' asteroids found sharing Neptune's orbit
Three new objects locked into roughly the same orbit as Neptune—called "Trojan" asteroids—have been found by researchers from the Carnegie Institution's Department of Terrestrial Magnetism (DTM) and the Gemini Observatory in Hilo, Hawaii. view more (2006-06-16)
Astronomers discover most Earth-like extrasolar planet yet
The world's preeminent planet hunters have discovered the most Earth-like extrasolar planet yet: a possibly rocky world about 7.5 times as massive as the Earth. view more (2005-06-14)
Tycho's Remnant Provides Shocking Evidence for Cosmic Rays
Astronomers have found compelling evidence that a supernova shock wave has produced a large amount of cosmic rays, particles of mysterious origin that constantly bombard the Earth. view more (2005-09-23)
Milky Way's Giant Black Hole Awoke from Slumber 300 Years Ago
Using NASA, Japanese, and European X-ray satellites, a team of Japanese astronomers has discovered that our galaxy's central black hole let loose a powerful flare three centuries ago. view more (2008-04-16)
Astronomers see double
A giant telescope with a whopping 8-metre diameter light collecting mirror opened its Cyclops eye on the Universe today [18 January]. Perched on the desolate summit of Cerro Pachon in the Chilean Andes at a height of 2737 metres [8,895 feet] the Gemini South telescope is an identical twin of Gemini North in Hawaii. The two telescopes, located each... view more... (2002-01-17)
Astronomers Pioneer New Method For Probing Exotic Matter
Using European and Japanese/NASA X-ray satellites, astronomers have seen Einstein's predicted distortion of space-time around three neutron stars, and in doing so they have pioneered a groundbreaking technique for determining the properties of these ultradense objects. view more (2007-08-28)
Cassiopeia A comes alive across time and space
Two new efforts have taken a famous supernova remnant from the static to the dynamic. A new movie of data from NASA's Chandra X-ray Observatory shows changes in time never seen before in this type of object. A separate team will also release a dramatic three-dimensional visualization of the same remnant. view more (2009-01-06)
Discovery of most recent supernova in our galaxy
The most recent supernova in our Galaxy has been discovered by tracking the rapid expansion of its remains. This result, using NASA's Chandra X-ray Observatory and NRAO's Very Large Array (VLA), has implications for understanding how often supernovas explode in the Milky Way galaxy. view more (2008-05-15)
SuperWASP begins the search for thousands of new planets
A consortium of astronomers is tomorrow (April 16th) celebrating the commissioning of the SuperWASP facility at the astronomical observatory on the island of La Palma in the Canary Islands, designed to detect thousands of planets outside of our own solar system. Only about a hundred extra-solar planets are currently known, and many questions about... view more... (2004-04-15)
A Glimpse of the Young Milky Way
VLT UVES Observes Most Metal-Deficient Star Known [1] A faint star in the southern Milky Way, designated HE 0107-5240, has been found to consist virtually only of hydrogen and helium. It has the lowest abundance of heavier elements ever observed, only 1/200,000 of that of the Sun - 20 times less than the previous record-holding star.... view more... (2002-10-28)
Amateurs and professionals combine observations to produce detailed picture of double asteroid
Roping together observations from the world's largest telescopes as well as the small instrument of a local backyard amateur, astronomers have assembled the most complete picture yet of a pair of asteroids whirling around one another in a perpetual pas de deux. view more (2007-03-30)
Chandra independently determines Hubble constant
A critically important number that specifies the expansion rate of the Universe, the so-called Hubble constant, has been independently determined using NASA's Chandra X-ray Observatory. view more (2006-08-10)
Solar System's Young Twin Has Two Asteroid Belts
Astronomers have discovered that the nearby star Epsilon Eridani has two rocky asteroid belts and an outer icy ring, making it a triple-ring system. The inner asteroid belt is a virtual twin of the belt in our solar system, while the outer asteroid belt holds 20 times more material. Moreover, the presence of these three rings of material implies... view more... (2008-10-28)
Scientists Probe Black Hole's Inner Sanctum
How does matter spiral its way to the center of a galaxy and into the mouth of a supermassive black hole? view more (2006-01-10)
Astronomers find first habitable Earth-like planet
Astronomers have discovered the most Earth-like planet outside our Solar System to date, an exoplanet with a radius only 50% larger than the Earth and capable of having liquid water. view more (2007-04-25)
