An amazing new NASA video shows two super-dense neutron stars tearing each other apart in a cataclysmic cosmic merger that ultimately forms a black hole.
13 May 2014, 11:09 AM ET
In this simulation, 2 neutron stars weigh in at 1.4 and 1.7 solar masses and are separated by only 11 miles. Intense tidal forces pull the stars apart as they spiral towards each other and the black hole is formed amidst the chaos.

The most powerful particle accelerator in the world, the Large Hadron Collider, has not yet created any black holes as some have feared, researchers say. Even it did, there is no danger of those black holes destroying Earth, scientists find.
30 April 2014, 07:09 AM ET
Scientists have been on the hunt for dark matter for decades. A new hypothesis now suggests that the strange invisible stuff could be made of microscopic, or quantum, black hole atoms.

Why can't anything travel faster than the speed of light? Do black holes really suck? And why is the universe expanding? These are just a few of the questions author and astrophysicist Jeffrey Bennett answers in his new book, "What is Relativity?"
22 April 2014, 02:00 PM ET
Many people with a basic knowledge of physics know that Einstein developed the theory of relativity, yet few people actually understand what it means. But author and astrophysicist Jeffrey Bennett relativity should be something anyone can understand.

A newly released documentary brings the hunt for ripples in the fabric of space-time — called gravitational waves — into focus, and you can watch it live on Space.com.
15 April 2014, 09:35 AM ET
On Tuesday (April 15), Space.com will premiere a new documentary "LIGO, A Passion for Understanding" by filmmaker Kai Staats, which follows scientists using the Laser Interferometer Gravitational-wave Observatories (LIGO) to hunt for gravitational waves.
14 April 2014, 12:14 PM ET
A powerful scientific tool set to come online in 2015 could help scientists spot gravitational waves, ripples in space-time born from violent cosmic crashes light-years from Earth.
11 April 2014, 01:00 PM ET
The ripples from violent cosmic collisions can be felt far across the universe, and thanks to a new, sensitive detector expected to start collecting data next year, scientists might be able to see evidence of those ripples from Earth for the first time.

While the supernova remnant, known as DEM L241, has been known since the 1970s, the companion star remained invisible until NASA's Chandra X-Ray Observatory recently examined the region.
09 April 2014, 03:18 PM ET
When two stars collide or a massive star blows up the fabric of the universe warps and springs back, sending gravitational waves across the cosmos. The wave motion would be very tiny. But to watch it, scientists must build very large instruments.
01 April 2014, 10:38 AM ET
A new movie premiering April 15 documents the science and people behind an amazing astronomical tool designed to catch sight of incredible, violent cosmic events trillions of miles from Earth.
31 March 2014, 11:57 AM ET
A close look by NASA's Chandra X-ray Observatory at the debris field of supernova explosion DEM L241 in the Large Magellanic Cloud has revealed a young star tightly orbiting either a tiny neutron star or a black hole. Read more: http://goo.gl/xT14vA

The central black holes in dwarf galaxies — the "seeds" that grow into the monsters at the core of the Milky Way and other large galaxies — are probably surprisingly weighty, containing 1,000 to 10,000 times the mass of our sun, a new study reports.
28 March 2014, 11:15 AM ET
Host Neil deGrasse Tyson will explore the ways light, time and gravity effect our perceptions of the universe as he travels faster than the speed of light and into the depths of a black hole on the next episode of Cosmos: A Sky Full of Ghosts.
20 March 2014, 08:07 PM ET
As the search effort for the missing Malaysia Flight MH370 continues, some questionable theories are being floated for the strange disappearance of the passenger jet, including — it seems — black holes.
17 March 2014, 10:45 AM ET
Gravitational waves are the "smoking gun" of the Big Bang. Predicted by Albert Einstein's theory of general relativity in 1916, a massive object like Earth distorts space-time around it like a bowling ball dropped on a trampoline.
13 March 2014, 07:46 AM ET
Hundreds of “rogue” wandering black holes may dwell in the Milky Way – and now Harvard University researchers say they know how to detect them. The discovery of these strange objects could shed light on the formation of the Milky Way and other galaxies.
05 March 2014, 03:20 PM ET
Astronomers have calculated how fast a distant supermassive black hole rotates, clocking it at nearly half the speed of light. A fortuitious lineup of cosmic objects allowed scientists to measure the mind-boggling spin rate.
04 March 2014, 07:00 AM ET
Inside black holes dwell quantum remains of the stars from which they were formed, say a group of scientists, who also predict that these stars can later emerge once the black hole evaporates.

27 February 2014, 02:05 PM ET
Black holes can blast their surroundings with much stronger winds than previously thought, scientists say. The discovery will help better model the evolution of black holes over time, and help uncover the huge influence they can have on host galaxies.

This cool space wallpaper shows a composite view of the giant elliptical galaxy NGC 1399. The stellar component, as observed at optical wavelengths, is shown in white at the center of the image.
26 February 2014, 11:58 AM ET
Powerful jets generated by supermassive black holes could be quenching star formation in elliptical galaxies, forcing them to appear "red and dead," a new study reports.

Over the past few days, the media has cried out the recent proclamation from Stephen Hawking that black holes, a mystery of both science and science fiction, do not exist.
28 January 2014, 03:39 PM ET
On the heels of his bombshell claim that black holes — as scientists have traditionally thought of them — may not exist, Stephen Hawking will tell the story of his life in a new documentary that premieres tonight (Jan. 29) at 10:00 p.m. EST on PBS.
28 January 2014, 03:12 PM ET
Famed astrophysicist Stephen Hawking has shaken up the popular science world with his newest study about the basic nature of black holes, but is his idea revolutionary? Some scientists aren't convinced.
28 January 2014, 12:05 PM ET
To resolve a paradox between quantum mechanics and general relativity, Stephen Hawking has released a new paper arguing that light can, in fact, escape from black holes eventually, doing away with the notion of an event horizon.
25 January 2014, 09:15 AM ET
Black holes are mysterious objects in space where not even light can escape. But what are they really? Can we even ever truly know?
25 January 2014, 09:02 AM ET
On reading a new paper by Stephen Hawking that appeared online this week, you would have been forgiven in thinking the world-renowned British physicist was spoofing us. Hawking's unpublished work declares: 'There are no black holes.'
