A spinning neutron star periodically swings its radio (green) and gamma-ray (magenta) beams past Earth in this artist's concept of a black widow pulsar. The pulsar heats the facing side of its stellar partner to temperatures twice as hot as the sun's surface and slowly evaporates it. Photo: NASA/Goddard Space Flight Center/Handout via Reuters

Gluttonous cosmic 'black widow' is heaviest-known neutron star

Gluttonous cosmic 'black widow' is heaviest-known neutron star

Astronomers have observed the most massive known example of an object called a neutron star, one classified as a "black widow" that got particularly hefty by gobbling up most of the mass of a stellar companion trapped in an unhappy cosmic marriage.

Russia signals space station pullout; NASA says it's not official yet

Russia's new space chief announced on Tuesday his country plans to withdraw from the International Space Station after 2024, but senior NASA officials said Moscow has not formally conveyed an intent to end its two-decade-old orbital partnership with the United States.

An artist’s impression showing what the binary star system VFTS 243 – containing a black hole and a large luminous star orbiting each other - might look like if we were observing it up close is seen in this undated handout image. The system, which is located in the Tarantula Nebula in the Large Magellanic Cloud galaxy, is composed of a hot, blue star with 25 times the sun’s mass and a black hole, which is at least nine times the mass of the sun.

Scientists find an exotic black hole deemed a 'needle in a haystack'

Astronomers have spotted in a galaxy adjacent to our Milky Way what they are calling a cosmic "needle in a haystack" - a black hole that not only is classified as dormant but appears to have been born without the explosion of a dying star.

Webb space telescope opens door to discoveries still unimagined

The powerful James Webb Space Telescope's inaugural batch of images has opened a new chapter of cosmic exploration, but astronomers say the observatory's most consequential discoveries may well be those they have yet to even imagine.

Meet the 'zombie star' that survived a supernova blast

Astronomers have observed in a relatively nearby galaxy a star that not only survived what ordinarily should have been certain death - a stellar explosion called a supernova - but emerged from it brighter than before the blast.

A composite image shows the star-forming region called 30 Doradus, also known as the Tarantula Nebula in this undated handout picture. The background image, taken in the infrared, was captured by the HAWK-I instrument on ESO's Very Large Telescope (VLT) and the Visible and Infrared Survey Telescope for Astronomy (VISTA) and shows bright stars and light, pinkish clouds of hot gas. The bright red-yellow streaks superimposed on the image come from radio observations taken by the Atacama Large Millimeter/submillimeter Array (ALMA), revealing regions of cold, dense gas that have the potential to collapse and form stars.

So long, Internet Explorer. The browser retires today

Internet Explorer is finally headed out to pasture. As of Wednesday, Microsoft will no longer support the once-dominant browser that legions of web surfers loved to hate — and a few still claim to adore. The 27-year-old application now joins BlackBerry phones, dial-up modems and Palm Pilots in the dustbin of tech history.

Astronomers ponder 'cosmic mystery' over powerful radio wave bursts

Powerful bursts of radio waves emanating from a distant dwarf galaxy that were detected using a massive telescope in China are moving scientists closer to solving what one called a "cosmic mystery" that has lingered for years.
