Latest RS Ophiuchi Stories
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.
Hubble has obtained the first direct optical images of the aftermath of a recent titanic explosion that took place in a star system 5,000 light years from Earth.
A team of astronomers from the UK and Germany have found that a nuclear explosion on the surface of a star 5,000 light years from Earth resulted in a blast wave moving at over 1,700 km per second.
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.
