Latest Ophiuchus constellation Stories
A massive star flung away from its former companion is plowing through space dust.
We know of about 150 of the rich collections of old stars called globular clusters that orbit our galaxy, the Milky Way.
Astronomers using the twin 10-meter telescopes at the WM Keck Observatory in Hawaii have explored one of the most compact dust disks ever resolved around another star.
Using the NASA / ESA Hubble Space Telescope (HST), an international team of astronomers have taken the first optical images of a dramatic stellar outburst and discovered a peanut-shaped bubble expanding rapidly into space.
Explosions of small stars, long thought to create stellar dust, actually sweep dust away, scientists discovered. For years, researchers have observed swirling dust clouds around systems called recurring novas, which periodically explode.
First results from a new NASA-funded scientific instrument at the W. M. Keck Observatory in Hawaii are helping scientists overturn long-standing assumptions about powerful explosions called novae and have produced the first unified model for a nearby nova called RS Ophiuchi.
The cast of exoplanets has an extraordinary new member. Using ESO's telescopes, astronomers have discovered an approximately seven-Jupiter-mass companion to an object that is itself only twice as hefty.
Records show that this so-called recurrent nova, RS Ophiuchi (RS Oph), has previously reached its current level of brightness five times in the last 108 years, most recently in 1985.
The existence of extrasolar planets has become common knowledge in the past decade. But in the mid-20th Century, the search for worlds orbiting other stars got off to a rocky start. Alan Boss, an astronomer with the Carnegie Institution of Washington, recounts the early days of extrasolar planet-hunting.
