Japanese researchers have proposed a new model for the formation of primordial black holes that could help explain the mysteries of dark matter and the early universe.

Asteroid 2008 XH is estimated to be around 102.5 meters in diameter. That makes it around 54 times the size of former US president Donald Trump.

Near-Earth asteroids (NEAs) tend to move very fast, which makes it hard to take precise images of them with telescopes. Researchers from China and Ukraine got around this with time delay integration.

A comet was seen flying over Spain and Portugal over the weekend as it impacted the atmosphere before burning up over the Atlantic Ocean.

Massive stars should not be able to have magnetic fields, but around 7% of them do anyway. A recent study found that this could be caused by stellar mergers.

Total solar eclipses are rare, not often occurring in the same place for a very long time. What makes it special? Why can't we look directly at it? Here's what you should know.

Weizmann scientists chronicle the earliest stages of a supernova.

Scientists at Israel's Weizmann Institute of Science got lucky and managed to spot a star in a nearby galaxy go supernova, able to make a portrait of the star's last days.

Asteroid 2021 CF6 will pass the Earth on March 25 in time for the Shushan Purim holiday. It's the size of 89 wolverines – the animal, not the superhero or the University of Michigan team (go blue!)

Asteroid 2024 FK1 is set to pass the Earth soon. The Jerusalem Post social media manager Noemi Szakács has asked me to measure it in French fries, so here it is.
