Euclid Mission: Bringing the dark universe to light

[ad_1] The Euclid mission, being undertaken by the European Space Agency (ESA), aims to illuminate the hidden aspects of our universe. It is expected to shed light on two enigmatic forces known as dark matter and dark energy. These entities, which remain undetectable through direct observation, exert significant influence on the behavior of galaxies, their rotation, and the expansion of the universe itself.To gain a deeper understanding of the nature of dark matter and dark energy, scientists require an instrument capable of closely examining the impact these forces have had on galaxies, galaxy clusters, and the overall expansion of the universe. And Euclid has emerged as the ideal solution for this pursuit. By generating a comprehensive 3D map of the universe, with the added dimension ...

Astronomers observe intra-group light, an elusive glow between distant galaxies

[ad_1] Researchers not only detected the intra-group light but were able to study and tell the story of the stars that populate it. An international team of astronomers have turned a new technique onto a group of galaxies and the faint light between them known as 'intra-group light' to characterise the stars that dwell there. Lead author of the study published in MNRAS, Dr Cristina Martinez-Lombilla from the School of Physics at UNSW Science, said "We know almost nothing about intra-group light. "The brightest parts of the intra-group light are ~50 times fainter than the darkest night sky on Earth. It is extremely hard to detect, even with the largest telescopes on Earth -- or in space." Using their sensitive technique, which eliminates light from all objects except that from t...

This bizarre object is FASTER than light? What did NASA Hubble Space Telescope catch?

[ad_1] NASA Hubble Space Telescope thought it spotted something that should not exist, which was travelling at a mind-altering rate 7 times faster than light! On Earth, we have created some really fast objects. For instance, the speed of a bullet out of a gun can be as high as 4,200 kilometers per hour, which is three times the speed of sound. But it is not even the fastest thing. The fastest man-made object would be the NASA Parker Solar Probe spacecraft which reached a speed of 535,000 kilometers per hour using the Sun's gravity! Now, that is fast. But you would be surprised to know that it is just 0.05% of the speed of light (300,000 kilometers per second). So, you can imagine just how fast light really is. And till now, it was surmised that nothing can travel faster than light. Bu...

Astronomers see BRIGHTEST flash of light EVER; black hole to blame

[ad_1] Astronomers have observed the brightest flash of light ever seen, from an event that occurred 2.4 billion light years from Earth and was likely triggered by the formation of a black hole.The burst of gamma-rays -- the most intense form of electromagnetic radiation -- was first detected by orbiting telescopes on October 9, and its afterglow is still being watched by scientists across the world. Astrophysicist Brendan O'Connor told AFP that gamma-ray bursts that last hundreds of seconds, as occurred on Sunday, are thought to be caused by dying massive stars, greater than 30 times bigger than our Sun. The star explodes in a supernova, collapses into a black hole, then matter forms in a disk around the black hole, falls inside, and is spewed out in a jet of energy that travels at 99...

NASA James Webb Space Telescope looks into the past! Does it reveal secrets of the universe?

[ad_1] NASA James Webb Space Telescope has been touted to look into the past and understand the origin of the universe. But how is it possible? The NASA James Webb Space Telescope has changed the way we look at space. Ever since we saw its first images on July 12, the space telescope has been mesmerizing us with its stunning never-seen-before images. Recently, the tech marvel captured the first ever clear image of Neptune and it showcased the magnificent rings surrounding it. Not only that but it has shown us distant galaxies and star clusters in a way that scientists didn't think was possible. And it does that using two of its crucial instruments called Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI). They c...
