Black Hole

Every galaxy holds a black hole whose gravitational field is extremely intense. However, that gravitational field affects only a small region around the center of the Universe. According to theories, the growing black holes generate enough energy to heat up and drive out the gas within galaxies to great distances.…

As the name suggests, supermassive black holes have masses ranging from one million to 10 billion solar masses. Sometimes, SMBHs are quiet and invisible, which makes it quite challenging to observe directly. But when a material is falling into their massive maws, they blaze with radiation, putting out more light…

If such an object a mere 1,000 times bigger than an atom passed through your body, the result would not be pretty Credit: George Peters Getty Images In the infant universe, a substantial enhancement in the radiation density on the scale of the cosmic horizon could have made some small…

A composite image of the supernova 1E0102.2-7219 contains X-rays from Chandra (blue and purple), visible light data from VLT’s MUSE instrument (bright red), and additional data from Hubble (dark red and green). A neutron star, the ultra dense core of a massive star that collapses and undergoes a supernova explosion,…

Doing astronomy with ripples in spacetimeGeneral relativity predicts that moving massive objects generate gravitational waves, ripples in spacetime that propagate at the speed of light. Direct detection of gravitational waves was first announced in February of 2016. Vitale reviews the scientific results of gravitational wave astronomy over the subsequent 5…

The ACT government has failed community legal centres by refusing to support a motion in the territory's parliament calling for an ongoing funding commitment, the opposition says. But Attorney-General Shane Rattenbury told the Legislative Assembly on Wednesday afternoon the ACT government could not support the motion before funding was considered…

MARCIA DUNN, AP Aerospace Writer May 28, 2021Updated: June 1, 2021 9:55 p.m. This false-color X-ray and radio frequency image made available by NASA on Friday, May 28, 2021 shows threads of superheated gas and magnetic fields at the center of the Milky Way galaxy. X-rays detected by the NASA's Chandra X-ray…

Last year, just for the heck of it, Scott Field and Gaurav Khanna tried something that wasn’t supposed to work. The fact that it actually worked quite well is already starting to make some ripples. Field and Khanna are researchers who try to figure out what black hole collisions should…
