Integral spots matter a millisecond from doom
— 28 Mar 2011 18:07 | AstronomyESA's Integral gamma-ray observatory has spotted extremely hot matter just a millisecond before it plunges into the oblivion of a black hole. But is it really doomed? These unique observations…
Cassini returns images of bright jets at Enceladus
— 2 Dec 2010 20:07 | AstronomyNASA's Cassini spacecraft successfully dipped near the surface of Saturn's moon Enceladus on Nov. 30. Though Cassini's closest approach took it to within about 48 kilometres (30 miles)…
Young-star discovery hints magnetism common to all cosmic jets
— 26 Nov 2010 19:34 | AstronomyAstronomers have found the first evidence of a magnetic field in a jet of material ejected from a young star, a discovery that points toward future breakthroughs in understanding the…
'Russian doll' galaxy reveals black holes' true power
— 24 Nov 2010 22:48 | AstronomyFollowing a study of what is in effect a miniature galaxy buried inside a normal-sized one - like a Russian doll - astronomers using a CSIRO telescope have concluded that massive black…
Getting bubbles out of fuel pumps
— 17 Nov 2010 10:03 | PhysicsFor more than 250 years, researchers have known that under certain conditions vapour bubbles can form in fluids moving swiftly over a surface. These bubbles soon collapse with such…
Atmospheric pressure plasma jet from a grounded electrode
— 25 Aug 2010 11:29 | PhysicsBecause they are portable and easy to operate at ambient temperatures, cold atmospheric pressure plasma jets (APPJs) should find innovative applications in biomedicine, materials science…
Black hole blows big bubble
— 8 Jul 2010 08:15 | AstronomyCombining observations made with ESO's Very Large Telescope and NASA's Chandra X-ray telescope, astronomers have uncovered the most powerful pair of jets ever seen from a stellar black…
RXTE homes in on a black hole's jets
— 2 Jul 2010 10:47 | AstronomyFor decades, X-ray astronomers have studied the complex behaviour of binary systems pairing a normal star with a black hole. In these systems, gas from the normal star streams toward…
Aircraft cause precipitation, hole-punch clouds
— 15 Jun 2010 02:26 | EnvironmentAs turboprop and jet aircraft climb or descend under certain atmospheric conditions, they can inadvertently seed mid-level clouds and cause narrow bands of snow or rain to develop and…
Backwards black holes might make bigger jets
— 2 Jun 2010 14:57 | AstronomyGoing against the grain may turn out to be a powerful move for black holes. New research suggests supermassive black holes that spin backwards might produce more ferocious jets of gas.…
