The Hubble Space Telescope is a Powerful Science Instrument Despite its Age

This Hubble image shows a supernova named SN 2022aajn in a distant galaxy about 600 million light-years away with the unwieldy name of WISEA J070815.11+210422.3. However, the obtuse yet scientifically descriptive names aren’t what’s important. What’s important is that SN 2022aajn is a Type 1a supernova, also known as a standard candle, and this image … Read more

James Webb Space Telescope catches monster black hole napping after ‘overeating’ in the early universe

Napping after overfeeding on food is a dilemma many of us will be fortunate to face on Christmas Day. New research has shown that, billions of years ago, some early black holes also had to nap after overindulging. Using the James Webb Space Telescope (JWST), astronomers spotted a dormant supermassive black hole that existed just … Read more

Dramatic changes on Uranus, Neptune, Saturn and Jupiter revealed in 10 years of Hubble Telescope images (video)

The Hubble Space Telescope has spent more than thirty years providing some of the most incredible images of the known universe, but it’s only for the last ten that scientists have pointed its gaze at our solar system’s outer planets to observe them like never before. For the past decade, NASA’s Outer Planet Atmospheres Legacy … Read more

‘Our understanding of the universe may be incomplete’: James Webb Space Telescope data suggests we need a ‘new cosmic feature’ to explain it all

New observations from the James Webb Space Telescope (JWST) have corroborated data from its predecessor, the Hubble Space Telescope, to determine something is missing from our recipe of the cosmos. The JWST conducted its largest survey yet of the accelerating expansion of the cosmos as scientists attempt to discover why the universe is expanding faster … Read more
