Best evidence of rare black hole captured

Posted by in category: cosmology

Scientists have been able to prove the existence of small black holes and those that are super-massive but the existence of an elusive type of black hole, known as intermediate-mass black holes (IMBHs) is hotly debated. New research coming out of the Space Science Center at the University of New Hampshire shows the strongest evidence to date that this middle-of-the-road black hole exists, by serendipitously capturing one in action devouring an encountering star.

Researchers capture best ever evidence of rare black hole

Posted by in category: cosmology

ESA’s XMM-Newton observatory has discovered the best-ever candidate for a very rare and elusive type of cosmic phenomenon: a medium-weight black hole in the process of tearing apart and feasting on a nearby star.

There are various types of black hole lurking throughout the Universe: massive stars create stellar-mass black holes when they die, while galaxies host supermassive black holes at their centres, with masses equivalent to millions or billions of Suns.

Lying between these extremes is a more retiring member of the black hole family: intermediate-mass black holes. Thought to be seeds that will eventually grow to become supermassive, these black holes are especially elusive, and thus very few robust candidates have ever been found.

A Black Hole Ate A Star And Left Crumbs Of Light For Astronomers To Discover

Posted by in category: cosmology

Black holes are notoriously messy eaters.


Using more than ten years of data, astronomers discovered traces of an unlucky star that got too close to a black hole. Because this event was partly hidden from us by dust, this discovery shows how we might find other cases of star-eating black holes.

Chandra Space Telescope: Revealing the Invisible Universe

Posted by in categories: climatology, cosmology

The Chandra X-Ray Observatory is a NASA telescope that looks at black holes, quasars, supernovas, and the like – all sources of high energy in the universe. It shows a side of the cosmos that is invisible to the human eye.

After more than a decade in service, the observatory has helped scientists glimpse the universe in action. It has watched galaxies collide, observed a black hole with cosmic hurricane winds, and glimpsed a supernova turning itself inside out after an explosion.

The telescope – billed as one of NASA’s Great Observatories along with the Hubble Space Telescope, Spitzer Space Telescope and the Compton Gamma Ray Observatory – has been a public relations tool for the agency, as well. Its pictures are frequently used by NASA in press releases.
