Astronomers have captured a “zoomed-in” image of a star outside the Milky Way for the first time. The team brought the vast red supergiant star designated WOH G64 into focus using the Very Large Telescope  Interferometer (VLTI). WOH G64 is located a staggering 160,000 light-years away in the Large Magellanic Cloud (LMC), a satellite dwarf galaxy companion of the Milky Way. Astronomers have known of the existence of this star for some time, and it has earned the nickname the “behemoth star” because it is an incredible 2,000 times the…

When the bright star Betelgeuse explodes, it will be an impressive sight. The stellar explosion, known as a supernova, will be brighter than any planet and almost as bright as the full moon. It will be visible during the day, and you could read a book to its light at midnight. It will last a few months before fading away, as all supernovas do. But it won’t be dangerous. For that, it would have to be much, much closer; Betelgeuse is roughly 650 light-years away. So are there any stars…

Using the James Webb Space Telescope, astronomers have discovered that planet-forming disks in the Orion nebula actually surround “failed stars,” or brown dwarfs. This is the first confirmation that planet-forming, flattened clouds of gas and dust called “protoplanetary disks” surround these peculiar cosmic objects. The team discovered this while using the James Webb Space Telescope (JWST) to follow up on observations of protoplanetary disks, or “proplyds,” illuminated by ultraviolet light in the Orion Nebula. Those observations were collected by the Hubble Space Telescope. These findings could help scientists understand how…

Using Europe’s Gaia space telescope, astronomers have identified 55 runaway stars being ejected at high speeds from a densely packed young cluster in the Large Magellanic Cloud (LMC), a satellite galaxy of our own Milky Way. This is the first time so many stars have been seen escaping from a single star cluster. The star cluster R136, located around 158,000 light-years away, is home to hundreds of thousands of stars and sits in a massive region of intense star formation in the LMC. It’s home to some of the biggest…

Using NASA’s exoplanet-hunting spacecraft, the Transiting Exoplanet Survey Satellite (TESS), scientists have spotted a record-breaking triple-star system so tightly bound that it could fit comfortably between the sun and its closest planet, Mercury. The system, designated TIC 290061484 contains twin stars that race around each other once every 1.8 Earth days as well as a third star that orbits this pair once every 25 Earth days. This triple star system’s super-tight orbit, located just under 5,000 light-years away in the constellation Cygnus, the swan, makes it a record-breaker.  The previous…
