Hubble Studies Small but Mighty Galaxy
Hubble Studies Small but Mighty Galaxy Hubble Space Telescope has released an image of NGC 4449, a small but mighty galaxy located 12.5 million light-years away. NGC 4449 is a starburst galaxy, meaning it’s forming new stars at a much faster rate than expected for its size, and this global burst of star formation is […]

Hubble Studies a Spiral’s Supernova Scene
Hubble Studies a Spiral’s Supernova Scene Hubble Space Telescope has captured an image of the spiral galaxy IC 758, which appears peaceful but hides a cataclysmic past. The galaxy was affected by a powerful supernova explosion in 1999, known as SN 1999bg, which marked the end of a massive star far more than the Sun’s […]

Far Out
Far Out Pismis 24, a star cluster located 8,000 light-years from Earth, was initially thought to be a single massive star. The star’s mass was estimated to be around 200-300 solar masses, making it potentially the most massive known star in the galaxy. However, measurements taken by NASA’s Hubble Space Telescope revealed that Pismis 24-1 […]

Do photons wear out? An astrophysicist explains light’s ability to travel vast cosmic distances without losing energy
Do photons wear out? An astrophysicist explains light’s ability to travel vast cosmic distances without losing energy Light travels at an incredible speed of 186,000 miles per second, making it the fastest thing in the universe. Despite its immense speed, light does not wear out or lose energy over vast cosmic distances because space is […]
