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.
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.
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.
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.
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.
A super-Earth known as Barnard b might be far more habitable than previously thought.
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.
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.
The more we learn about the expanding universe, the stranger it becomes.
‘This is the most beautiful and satisfactory explanation of creation to which I ever listened.’
Earth and Mars will be closer together in distance than they have for 15 years, making the Red Planet easily visible with the naked eye.
The story thus far… and the curious drama that is solar cycle #24.
Giant black hole has been eating a ‘star every two days’, scientists transfer memory between snails, child’s mummified hand mystery solved, and more.
Vexed astronomers all over the world have lambasted Rocket Lab, a private U.S./New Zealand-based aerospace development company, after it surreptitiously launched a satellite resembling a giant disco ball into the Read More…
Scientists have discovered a planet the size of Jupiter orbiting a star that’s only half the size of the sun, contradicting theories that a star so small could form a planet so large.
