An explosion in space so massive you'll be able to look up and see it in the night sky without a telescope could happen "any day now," a NASA expert said Wednesday.
Astronomers predict that the nova explosion could happen anytime between now and September. The last time this particular star system erupted was in 1946, Schaefer said, and another eruption will ...
The Space Variable Objects Monitor is a small X-ray telescope satellite for studying the explosions of massive stars by analysing the resulting gamma-ray bursts, developed by China National Space Administration (CNSA), Chinese Academy of Sciences (CAS) and the French Space Agency , [45] launched on 22 June 2024 (07:00:00 UTC).
As of 2012 there were an estimated 500,000 pieces of debris in orbit, [4] with 300,000 pieces below 2000 km . [1] Of the total, about 20,000 are tracked. [ 1 ] Also, about sixteen old Soviet nuclear space reactors are known to have released an estimated 100,000 NaK liquid metal coolant droplets 800–900 km up, [ 5 ] which range in size from 1 ...
[1] [2] Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire that killed an entire crew of three. There have also been some non-astronaut fatalities during spaceflight-related activities. As of 2025, there have been over 188 fatalities in incidents regarding spaceflight.

Multiple telescopes observed a rare cosmic explosion called a kilonova that created heavy elements in space, including some necessary for life. Explosion 1 million times brighter than the Milky ...
Very-high-energy gamma rays may be slowed down as they propagate through the quantum turbulence of space-time. [6] [7] The explosion took place 12.2 billion light-years (light travel distance) away. That means it occurred 12.2 billion years ago—when the universe was only about 1.5 billion years old.
