A pair of orbiting black holes millions of times the Sun’s mass perform a hypnotic dance in this NASA visualization. The movie traces how the black holes distort and redirect light emanating from the...

¿Qué es un agujero negro? Aún no lo tenemos muy claro.

Neutron stars are formed from the core of some starrs. Neutron stars generally have a radius of only around 12 km. With masses exceeding 1.4 times that of the Sun, these are some of the densest objects in the Universe. A tablespoonful of...

We all know the perfect, symmetrical and flawless galaxies Hubble has set its lense on, but there is also a catalogue dedicated to the most peculiar galaxies out there... The Arp Catalogue

Since Earth completes one revolution around the sun in 1 year, it would make sense to think that after the completion of year, Earth would be exactly at the same spot where it was at the beginning of the year, wouldn't it? But is it...

Measurements of unprecedented detail returned by Japan's Hitomi satellite have allowed scientists to track the motion of X-ray-emitting gas at the heart of the Perseus cluster of galaxies for the first time. The...

Black holes are often described as the monsters of the universe—tearing apart stars, consuming anything that comes too close, and holding light captive. Detailed evidence from NASA's Hubble Space Telescope, however, shows a...

We've learned about the lifetime of stars, and we saw that very high mass stars will leave behind a black hole when they die. What else can we say about black holes? Is there any other way to make a black hole besides waiting for a huge...

On Sept. 16, NASA's Swift satellite detected a rising tide of high-energy X-rays from a source toward the center of our Milky Way galaxy. The outburst, produced by a rare X-ray nova, announced the presence of a previously...

Learn all about quasars, extremely bright objects in outer space powered by black holes. This video explains how they were discovered, their connection to supermassive black holes, and their significance in understanding the early...

Astronomer Steve Eikenberry at the University of Florida is on the hunt for black holes. Using a custom built camera affixed to the Gemini South telescope in Chile, he is honing in on the supermassive black hole at the center of our...

Armed with state-of-the-art supercomputer models, scientists have shown that colliding neutron stars can produce the energetic jet required for a gamma-ray burst. Earlier simulations demonstrated that mergers could make black holes....

Ancient Polynesians may have crossed the Pacific to make contact with Native Americans from the region that is now Colombia

In this video, the teacher explains how to multiply numbers expressed in scientific notation. They review the concept of scientific notation and the rules for multiplying exponential expressions with the same base. The teacher provides...

A new computer simulation tracking dark matter particles in the extreme gravity of a black hole shows that strong, potentially observable gamma-ray light can be produced. Detecting this emission would provide astronomers with...

On Aug. 26, 2020, NASA’s Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that turned out to be one for the record books – the shortest gamma-ray burst (GRB) caused by the death of a...

LISA Pathfinder, a mission led by the European Space Agency (ESA) with contributions from NASA, has successfully tested a key technology needed to build a space-based observatory for detecting gravitational waves....

Astronomer Steve Eikenberry at the University of Florida is on the hunt for black holes. Using a custom built camera affixed to the Gemini South telescope in Chile, he is honing in on the supermassive black hole at the center of our...

Scientists have mapped the environment surrounding a black hole that is 10 times the mass of the Sun using NASA's Neutron star Interior Composition Explorer (NICER) payload aboard the International Space...

Here's just some of what we already know about neutron stars. An upcoming NASA mission will further investigate these unusual objects from the International Space Station. The Neutron star Interior Composition...

Tipler Cylinders? Wormholes? Ring Lasers? Is it possible to travel BACK in time? In this action packed episode, Dom is hunted down by a government agent who wants to know how he made a time machine.

The Hubble Space Telescope captured an image of a quasar named 3C 186 that is offset from the center of its galaxy. Astronomers hypothesize that this supermassive black hole was jettisoned from the center of its galaxy by...

Astronomers have found a so-called black neutron star that changes our understanding of both black holes and neutron stars.

Humanity is a clumsy species. How else can you explain all the times we've almost fumbled our way into extinction. From nuclear false alarms to poisoned crops, here are 10 Times The World Almost Ended By Accident.
