A 13.5-billion-year-old star, among the universe’s oldest, is quietly hiding in our galaxy. Key Takeaways: Astronomers have discovered one of the oldest stars in the universe, just 2,000 light-years away. This ancient red dwarf, 13.5 billion years old, formed from nearly pristine Big Bang material. The star’s low mass challenges the idea that the first…

Jupiter’s lightning bolts are three times more powerful than Earth’s strongest superbolts. Key Takeaways: NASA’s Juno spacecraft, Hubble, and Gemini Observatory are teaming up to study Jupiter’s storms. By combining space and ground-based telescopes, scientists are probing Jupiter’s deep atmosphere like never before. Juno detects radio waves from lightning, while Hubble and Gemini provide global…

A massive star 75 million light-years away has disappeared—without even leaving a supernova. Key Takeaways: A giant star in the Kinman Dwarf galaxy, once shining brightly, has mysteriously vanished. Scientists expected to see a supernova, but instead, the star simply faded from view. One possible explanation is that the star collapsed directly into a black…

NASA’s TESS telescope found a planet just 31 light-years away that could have liquid water. Key Takeaways: Astronomers have discovered a potentially habitable exoplanet, GJ 357 d, just 31 light-years away. This exoplanet orbits within its star’s habitable zone and could support liquid water if it has a thick atmosphere. GJ 357 d is at…

The lowest-mass binary ever found consists of two Jupiter-sized objects drifting freely through space. Key Takeaways: Astronomers have discovered a pair of free-floating planetary-mass objects traveling together in the Milky Way. This binary system, 2MASS J11193254–1137466AB, consists of two objects with just 3.7 Jupiter masses each. Scientists estimate the pair to be about 10 million…

Hundreds of black holes may be clustered just 3.3 light-years from the Milky Way’s core. Key Takeaways: Scientists have found evidence that hundreds of black holes may be densely packed around Sagittarius A*. X-ray data from the Chandra Observatory suggests at least 12 x-ray binaries near the galactic core. These binaries serve as tracers, hinting…

Sagittarius A* may have collided with another black hole 9 billion years ago, altering its spin. Key Takeaways: The Milky Way’s supermassive black hole, Sagittarius A*, is spinning rapidly and misaligned with the galaxy. Scientists now believe this unusual spin resulted from a massive black hole merger billions of years ago. Data from the Event…

TRAPPIST-1, a tiny star just 39 light-years away, hosts seven Earth-sized worlds. Key Takeaways: Scientists have discovered seven Earth-sized exoplanets orbiting the ultracool dwarf star TRAPPIST-1. Three of these planets lie in the habitable zone, where liquid water could potentially exist. The system is only 39 light-years away, making it one of the best places…

A massive underground lake, 20 km wide, has been found beneath Mars’ icy south pole. Key Takeaways Scientists have detected a subglacial lake of liquid water beneath the Martian south pole. The lake spans 20 km (12.4 miles) and is likely rich in salts, keeping it from freezing. The discovery was made using the Mars…
