In an unprecedented celestial event, NASA's Hubble Space Telescope (HST) captured the dramatic aftermath of colliding space rocks within a nearby planetary system.

Hubble has turned its sharp gaze on a compact, intensely blue dwarf galaxy about 13 million light years away, revealing a crowded nursery where massive stars are being forged at a furious pace. The new view captures a system so small and bright that it looks almost like a single star,

The Atacama Cosmology Telescope in Chile has released its final batch of data after 15 years — and it proves that the Hubble tension is very real.

Hubble is far from the only space telescope affected, and future astronomy craft will likely fare much worse. According to Borlaff and his team, bright streaks of light are projected to appear in 96 percent of the images from the European Space Agency’s ARRAKIHS, which is eying a launch window sometime in the 2030s.

In the cold dark of the constellation Ophiuchus, a faint, wraithlike shell of gas is quietly advertising the fate that awaits our own Sun. Astronomers call it the Little Ghost Nebula, a planetary nebula sculpted by a dying star that has shed its outer layers and left a hot stellar core blazing at the center.

While space telescopes are presumed safe from interference, a NASA-led study recently confirmed a major problem that is now ruining their images.
