Astronomers Discovered Something Near the Dawn of Time That Shouldn’t Exist
“It is a massive surprise,” said one astronomer who measured the high temperatures of gas in galaxy cluster that existed 12 billion years ago.

Astronomers discover the most powerful and distant cosmic ring ever seen
Astronomers have found the most distant and energetic “odd radio circle” ever detected — a massive double-ringed radio structure nearly 10 billion years old. The discovery, made with the help of citizen scientists using LOFAR, challenges theories that these cosmic rings are caused by black hole mergers. Instead, researchers suggest galactic superwinds may be to blame.
Surprisingly Dense Exoplanet Challenges Planet Formation Theories (PHOTOS, VIDEOS)
New detailed observations reveal a young exoplanet, orbiting a young star in the Hyades cluster, that is unusually dense for its size and age. Weighing in at 25 Earth-masses, and slightly smaller than Neptune, this exoplanet’s existence is at odds with the predictions of leading planet formation theories.
First Ever Image Of A Multi-Planet System Around A Sun-like Star Captured By ESO Telescope (VIDEO)
The European Southern Observatory’s Very Large Telescope (ESO’s VLT) has taken the first ever image of a young, Sun-like star accompanied by two giant exoplanets. Images of systems with multiple exoplanets are extremely rare, and — until now — astronomers had never directly observed more than one planet orbiting a star similar to the Sun. The observations can help astronomers understand how planets formed and evolved around our own Sun.
Scientists Discovered a Gigantic Structure in a Hidden Zone of Space (VIDEO)
An international team of scientists has discovered a filament of a fundamental structure known as the cosmic web hiding in the ‘Zone of Avoidance,’ and it’s one of the biggest structures ever seen by humans.
A Massive Star Has Seemingly Vanished from Space With No Explanation (VIDEO)
Astronomers are trying to figure out whether the star collapsed into a black hole without going supernova, or if it disappeared in a cloud of dust.
Super-Earths Discovered Orbiting Nearby Red Dwarf
The nearest exoplanets to us provide the best opportunities for study, including searching for evidence of life outside the Solar System. Astronomers have now detected a system of super-Earth planets orbiting the nearby star Gliese 887, the brightest red dwarf star in the sky. The newly discovered super-Earths lie close to the red dwarf’s habitable zone, where water can exist in liquid form.
Nearby Planet Could Support Primitive Life, Scientists Announce
A super-Earth known as Barnard b might be far more habitable than previously thought.
Inferno Planets & The Goldilocks Zone: Here Are Kepler’s Most Awesome Discoveries (PHOTOS, VIDEO)
Launched in 2009, Kepler’s mission was actually born in the early 80s as scientists began to turn their attention to finding planets with similar characteristics to home. Here are just some of the cool discoveries made possible due to the intergalactic telescope.
Giant Planets Around Young Star Raise Questions About How Planets Form
Researchers have identified a young star with four Jupiter and Saturn-sized planets in the most extreme range of orbits yet observed around it, the first time that so many massive planets have been detected in such a young system — raising interesting questions about how such a system might have formed.
