Greece’s Antikythera Mechanism upends timelines of technology

Researchers call the Antikythera Mechanism a 'computer' that 'breaks' the chronology of history, citing newly decoded functions uncovered long after its shipwreck.

Black Hole Blues: At the Edge of Time, Space, and No Return

Black Hole is an entity which produces so strong force of gravity that nothing even light can escape.

An artist's illustration shows a rapidly feeding black hole that is emitting powerful gas outflows.

Black holes can move and 'reawaken,' scientists say

The data suggest that the black hole launched powerful outflows months after the star’s destruction, showing that black holes can “reawaken” episodically.

Israeli research reveals a star's survival from black hole bout - and comeback for round two

A star in a distant galaxy was ripped apart by a supermassive black hole. But Israeli scientists say it survived and came back a second time - a discovery that upends scientific consensus.

NASA telescope catches black hole twisting captured star into donut shape

The telescope was not able to capture the whole process up close because the star that was swallowed was 300 million light years away.

Scientists discover pair of black holes sharing a galaxy-merger meal

The two black holes are extraordinarily close together, and are jointly feasting on the matter generated as a byproduct of the merging galaxies.

This artist’s conception shows the late-stage galaxy merger and its two central black holes. The binary black holes are the closest together ever observed in multiple wavelengths.

The collision of stars rockets scientists' understanding of physics

Scientists have detected cosmic "bursts" which indicate the occurrence of a celestial event where stars collided, merged and collapsed into a black hole.

Oscillating signals may help researchers predict neutron star collisions

Signals found in gamma-ray bursts could create a potential opportunity to study the properties of similar occurrences, according to a new study.

Black hole blasted Earth with near light-speed jet of matter - study

The jet of matter, appearing as a flash of light brighter than 1,000 trillion suns, originated from a supermassive black hole 8.5 billion light years away and traveled at 99.99% the speed of light.

New space observatory helps solve mystery involving enormous black holes

Using data from the recently deployed Imaging X-ray Polarimetry Explorer (IXPE) orbiting observatory, researchers were able to answer more unexplained questions.

Undetected black hole shreds apart star in dwarf galaxy

The shredding of the star, known as a “tidal disruption event” or TDE, produced a flare of radiation that briefly outshone the combined stellar light of the host dwarf galaxy.
