Hubble captures the dramatic end of a distant supernova

  • No comments
The Hubble Space Telescope has documented the remnants of the supernova SN 2022abvt in the distant galaxy LEDA 132905, more than 400 million light-years from Earth.
To mark the 100th anniversary of Edwin Hubble’s discovery of a Cepheid variable star, named V1, in the neighboring Andromeda galaxy, astronomers collaborated with the American Association of Variable Star Observers (AAVSO) to study the star. AAVSO observers followed V1 for six months, creating a graph—or light curve—that records the star’s periodic rise and fall in brightness. Based on this data, the Hubble Space Telescope was scheduled to observe the star during its weakest and brightest hours. Credit: NASA, ESA, Hubble Heritage Project (STScI, AURA), Robert Gendler.

The star that proved the universe is bigger than we imagined

A century ago, Edwin Hubble's discovery of the variable star V1 in the Andromeda Galaxy revealed a vast, expanding universe, becoming a turning point in our understanding of the cosmos.
Quasar J0742+2704 (center) became a topic of interest for astronomers in 2020 after it was discovered to have a new jet emanating from the disk around its supermassive black hole. The discovery was made using the Karl G. Jansky Very Large Array (VLA) radio observatory. Follow-up observations were subsequently made with other observatories, with the aim of determining the properties of the galaxy and understanding what might have powered the jet. **Credit:** NASA, ESA, Kristina Nyland (US Naval Research Laboratory); Image processing: Joseph DePascala (STScI).

Scientists are cracking the secrets of star formation by following the explosive trails of dead stars. This method could prove that all stars, everywhere in the universe, are created in the same way

This figure shows a stage in the merger of two galaxies that creates a single galaxy with two supermassive black holes at the center and surrounded by disks of hot gas. The black holes orbit each other for hundreds of millions of years as they merge to form a single supermassive black hole that sends out powerful gravitational waves. Credit: NASA/CXC/A.Hobart

Gravitational waves hint that the universe still has secrets

The facility, named JUNO, consists of a huge tank that surrounds an array of detectors. The container contains a substance that causes a scintillation which is recorded in the detectors and thus allows to identify a neutrino event, its type and mass, since the neutrino particles change
