Galaxy J1354

Black hole munched galactic leftovers, spewed stars, burped

The black hole at the centre of galaxy SDSS J1354+1327 sucked in gases, “burped” – and then repeated the display. As NASA explained in a statement: “The two-course meal for the black hole comes from a companion galaxy that collided with J1354 in the past. This collision produced a stream of stars and gas that links J1354 and …

Worcestershire's airborne electronics warfare wonderland

Geek's Guide to Britain When you first see the view from Croome's church, it looks like an English utopia. The landscape, designed by Lancelot "Capability" Brown during the 1750s, features a lake pretending to be river, winding lazily through fields dotted by scenic trees. To the left is Croome Court, a grand Palladian country house built over the red …

Boffins closer to solving what causes weird radio bursts from space

A neutron star or a massive black hole may be the source of mysterious and highly energetic radio pulses that light up skies across the universe. A paper published on Wednesday in Nature describes a particular fast radio burst (FRB) source. Scientists have spied about 30 FRBs so far, but FRB 121102 is the only signal source …

Boffins use inkjets to print explosives

As anybody who's emerged from a car crash in good shape can tell you, it's good to have some explosives around - they pop modern vehicles' air bags. Of course explosives are also hard to manufacture and handle, which is why researchers at Purdue University in the US tried to print them. The boffins believe they've cracked the …

Where did all that water go? Mars was holding it wrong, say boffins

Mars is dry, frozen and arid because its water reserves dried up. A large chunk of that water was lost when the planet’s magnetic field collapsed and it could no longer shield itself from the energetic solar rays. And top of this, research out this week shows that a portion of that liquid was absorbed by its rocks, too. How …
