telescope finds young stars in cosmic dance
A trio of newborn stars, 1,400 light-years away are taking part in a complex dance, as revealed by recent NASA Hubble Space Telescope (HST) observations. Two are now closely embracing each other, while the third has parted from their company. March 16, 2000 |
New
class of gamma ray objects found in Milky Way
The exotic world of gamma-ray astronomy has taken yet another surprising turn with the revelation that half the previously unidentified high-energy gamma ray sources in our own galaxy, the Milky Way, actually comprise a new class of mysterious objects. March 23, 2000 |
Powerful
jets stretch supernova remnant bubble
Two jets of high-speed particles from what appears to be either a black hole or neutron star are shooting off in opposite directions and punching their way into the supernova remnant that surrounds them, stretching what was once a spherical shell of shimmering gas into an egg-shaped remnant.

| 'Feeding'
mechanism discovered for black holes
Astronomers at Ohio State University used an innovative imaging technique to discover swirling masses of interstellar dust spiraling into the center of nearby galaxies. The researchers believe this interstellar dust is feeding supermassive black holes. March 29, 2000 |
Astronomers
find new, smaller planets orbiting distant stars
In a discovery that takes astronomers a step closer to finding other Earths orbiting other suns, researchers have found two objects slightly less massive than Saturn circling distant stars. March 29, 2000 |
Sun's
heartbeat may help unravel solar cycle mystery
Like blood pulsing in an artery, newly discovered currents of gas beat deep inside the Sun, speeding and slackening every 16 months. The solar "heartbeat" throbs in the same region of the Sun suspected of driving the 11-year cycle of solar eruptions.Scientists are hopeful that this pulse can help them unravel the origin and operation of the solar cycle.

Chandra reveal a nova of many colors
Images from different telescopes -- including NASA's two premier space observatories -- have been combined to create a multifaceted view of a supernova remnant, astronomers said this week. April 13, 2000 |
Astronomers peering across the universe have spotted the most distant quasar ever observed, an object 26 billion light-years away, researchers said on Thursday. April 14, 2000 |
Hubble
telescope sees galactic silhouettes
A new image from NASA's Hubble Space Telescope shows the unique galaxy pair called NGC 3314. Through an extraordinary chance alignment, a face-on spiral galaxy lies precisely in front of another larger spiral. This line-up provides the rare chance to visualize dark material within the front galaxy, seen only because it is silhouetted against the object behind. May 11, 2000 |
