Space oddity: Most distant rotating disc galaxy found

October 7, 2024369 Views

Researchers have discovered the most distant Milky-Way-like galaxy yet observed. Dubbed REBELS-25, this disc galaxy seems as orderly as present-day galaxies, but we see it as it was when the Universe was only 700 million years old. This is surprising since, according to our current understanding of galaxy formation, such early galaxies are expected to appear more chaotic. The rotation and structure of REBELS-25 were revealed using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner. The galaxies we see today have come a long way from their chaotic, clumpy counterparts that astronomers typically observe in the early Universe. “According to our understanding of galaxy formation, we expect most early galaxies to be small a...

Scientists discover planet orbiting closest single star to our Sun

Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), astronomers have discovered an exoplanet orbiting Barnard’s star, the closest single star to our Sun. On this newly discovered exoplanet, which has at least half the mass of Venus, a year lasts just over three Earth days. The team’s observations also hint at the existence of three more exoplanet candidates, in various orbits around the star. Located just six light-years away, Barnard’s star is the second-closest stellar system — after Alpha Centauri’s three-star group — and the closest individual star to us. Owing to its proximity, it is a primary target in the search for Earth-like exoplanets. Despite a promising detection back in 2018, no planet orbiting Barnard's star had been confirmed until now. This ar...

The Webb Space Telescope has captured a pair of intertwined galaxies glowing in the infrared. In this photo provided by NASA and the Space Telescope Science Institute, two interacting galaxies are captured by the Webb Space Telescope in the infrared. Scientists say the neighboring galaxies, nicknamed Penguin, right, and the Egg, left, have been tangled up for tens of millions of years. (NASA and Space Telescope Science Institute via AP) The observatory operated by NASA and the European Space Agency photographed the two galaxies 326 million light-years away, surrounded by a blue haze of stars and gas. A light-year is 5.8 trillion miles. The pictures, released Friday, marks the second anniversary of Webb’s science operations. The neighboring galaxies, nicknamed Penguin and the E...

A massive cradle of baby stars has been observed in new detail by a European space telescope, adding to its celestial collection of images. The European Space Agency released the photos from the Euclid observatory on Thursday. They were taken following the telescope’s Florida launch last year as a warm-up act to its main job currently underway: surveying the so-called dark universe. Star forming region Messier 78. Galaxy cluster Abell 2390. From its perch 1 million miles (1.6 million kilometers) from Earth, Euclid will spend the next several years observing billions of galaxies covering more than one-third of the sky. The shape and size of all these galaxies can help scientists understand the mysterious dark energy and dark matter that make up most of the universe. “Euc...

New Webb image captures clearest view of Neptune’s rings in decades

NASA's James Webb Space Telescope shows off its capabilities closer to home with its first image of Neptune. Not only has Webb captured the clearest view of this distant planet's rings in more than 30 years, but its cameras reveal the ice giant in a whole new light. Most striking in Webb's new image is the crisp view of the planet's rings – some of which have not been detected since NASA's Voyager 2 became the first spacecraft to observe Neptune during its flyby in 1989. In addition to several bright, narrow rings, the Webb image clearly shows Neptune’s fainter dust bands. Webb’s Near-Infrared Camera (NIRCam) image of Neptune, taken on July 12, 2022, brings the planet’s rings into full focus for the first time in more than three decades. IMAGE: NASA, ESA, CSA, STScI "It has been ...

The James Webb Space Telescope has revealed stunning details of the galaxy M74, nicknamed the Phantom Galaxy. New images of the spectacular Phantom Galaxy, M74, showcase the power of space observatories working together in multiple wavelengths. In this case, data from the NASA/ESA/CSA James Webb Space Telescope and the NASA/ESA Hubble Space Telescope complement each other to provide a comprehensive view of the galaxy. This image from the NASA/ESA/CSA James Webb Space Telescope shows the heart of M74, otherwise known as the Phantom Galaxy. Webb’s sharp vision has revealed delicate filaments of gas and dust in the grandiose spiral arms which wind outwards from the centre of this image. A lack of gas in the nuclear region also provides an unobscured view of the nuclear star cluster at ...

The world’s newest and biggest space telescope is showing Jupiter as never before, auroras and all. Scientists released the shots Monday of the solar system’s biggest planet. The James Webb Space Telescope took the photos in July, capturing unprecedented views of Jupiter’s northern and southern lights, and swirling polar haze. Jupiter’s Great Red Spot, a storm big enough to swallow Earth, stands out brightly alongside countless smaller storms. One wide-field picture is particularly dramatic, showing the faint rings around the planet, as well as two tiny moons against a glittering background of galaxies. This image provided by NASA shows a false color composite image of Jupiter obtained by the James Webb Space Telescope on July 27, 2022. The planet’s rings and some of its small...

Galaxies merger produces a spectacular cosmic dance

August 17, 2022385 Views

ESO telescope captures an event that started around a billion years ago ESO’s Very Large Telescope (VLT) has imaged the result of a spectacular cosmic collision — the galaxy NGC 7727. This giant was born from the merger of two galaxies, an event that started around a billion years ago. At its centre lies the closest pair of supermassive black holes ever found, two objects that are destined to coalesce into an even more massive black hole. Just as you may bump into someone on a busy street, galaxies too can bump into each other. But while galactic interactions are much more violent than a bump on a busy street, individual stars don’t generally collide since, compared to their sizes, the distances between them are very large. Rather, the galaxies dance around each other, with gravity ...

A sparkling landscape of baby stars. A foamy blue and orange view of a dying star. Five galaxies in a cosmic dance. The splendors of the universe glowed in a new batch of images released Tuesday from NASA’s powerful new telescope. The unveiling from the James Webb Space Telescope began Monday at the White House with a sneak peek of the first shot — a jumble of distant galaxies that went deeper into the cosmos than humanity has ever seen. Two full-color images from NASA's James Webb Space Telescope, a revolutionary apparatus designed to peer through the cosmos to the dawn of the universe, show composites made from images at Mid-Infrared (L) & Near-Infrared (R) and released July 12, 2022.

An international research team will survey the stars, star clusters, and dust that lie within 19 nearby galaxies Spirals are some of the most captivating shapes in the universe. They appear in intricate seashells, carefully constructed spider webs, and even in the curls of ocean waves. Spirals on cosmic scales – as seen in galaxies – are even more arresting, not only for their beauty, but also for the overwhelming amount of information they contain. How do stars and star clusters form? Until recently, a complete answer used to lie out of reach, blocked by gas and dust. Within the first year of operations, NASA’s James Webb Space Telescope will help researchers complete a more detailed sketch of the stellar life cycle with high-resolution infrared-light images of 19 galaxies.
