How many galaxies are there in the universe, and is it possible to compute them? As per BBC Sky and Night, the number of galaxies in the universe will be equal to the Universe’s size multiplied by the average number density of galaxies. In practice, estimating these two figures properly is tough.
The universe’s overall size is unknown. Recent studies suggest that the number of galaxies may be limitless, meaning that there are an endless number of galaxies.
Just 31 light-years away TechSpot is about to celebrate its 25th anniversary. TechSpot means tech analysis and advice you can trust. Why it matters: A team of international astronomers announced the discovery of an exoplanet that is both eerily similar and close to Earth on a galactic scale.
Above the islands of Hawaii o n January 28, a green laser was seen piercing the night sky, silently tracing a path towards the horizon like a stutter in the Matrix’s code.
The scene was caught on camera from a telescope atop Hawaii’s tallest peak.
You can check out the scanning laser in the footage below.
A newly discovered structure located deep in the heart of a thick cloud of gas and dust more than 450 light-years away is the signature of a pair of baby stars in the throes of formation.
A team of astronomers have identified a previously unseen bubble at the center of a stellar nursery called Barnard 18 in the Taurus molecular cloud complex, likely carved from the surrounding gas as two emerging stars therein formed and grew.
It’s only the second time astronomers have identified such a bubble with the ejection of material or ‘outflow’ associated with a growing star. The newly discovered structure could help scientists learn more about how stars affect their environment as they grow.
During a break from looking at planets around other stars, the European Space Agency’s CHaracterising ExOPlanet Satellite (Cheops) mission has observed a dwarf planet in our own Solar System and made a decisive contribution to the discovery of a dense ring of material around it.
The dwarf planet is known as Quaoar. The presence of a ring at a distance of almost seven and a half times the radius of Quaoar, opens up a mystery for astronomers to solve: why has this material not coalesced into a small moon?
The fate of galaxies is determined by the initial mass distribution at the birth of a new population of stars in the diverse and vast Universe. This relationship is referred to as the Initial Mass Function (IMF
In the field of astronomy, initial mass function (IMF) is an empirical function that details the distribution of stellar masses in a newly formed population of stars.
A tech demo launching later this year are the first steps towards a possible communication system based on quantum entanglement.
One of the most interesting stars in the Milky Way is still serving up more than its fair share of intrigue.
In October 2020, SGR 1935+2154, the magnetar responsible for spitting out radio signals never before detected in our home galaxy, unexpectedly slowed down.
Now, scientists believe the rotational slowdown could be evidence of a volcano-like eruption on its surface, spewing material out into space that altered the star’s environment enough to decelerate the spinning of the planet minutely.
Google’s wannabe rival to ChatGPT is off to a shaky start after its launch video featured a glaring error about the JWST and exoplanets. As a result of the blunderin parent company Alphabet plunged by around $100 billion on Wednesday.
In a promo video posted on Wednesday, Googles’s new artificial intelligence (AI) chatbot, Bard, was asked to describe the discoveries made by JWST to a nine-year-old child. It replied that it was the first telescope to ever take pictures of a planet outside of the Solar System.
Unfortunately, however, that is not true.
Scientists discovered a mysterious light in what they previously believed was a darker region of space. The light, which James Webb picked up, was initially invisible when Hubble observed the area. But scientists aren’t quite sure what caused this mysterious light in space, so they’re still searching.
