Astronomers using the Atacama Large Millimeter Array (ALMA) have spotted presence of a disc around a Jupiter-like exoplanet 400 light years away that could provide the raw material for up to three satellites the size of Earth’s Moon.
That incredible distance made the original discoverers of the planet back in 2011 think it was “rogue”. But a new research shows that the planet is in fact gravitationally bound to a star, just as an absurdly far distance.
Researchers report the discovery of a super-Earth orbiting the star GJ 740, a red dwarf star situated some 36 light years from Earth. Its mass is around 3 times the mass of Earth.
A new study of the seven Earth-sized exoplanets around TRAPPIST-1 indicate that all 7 planets are extremely similar to each other in makeup, but potentially quite different from Earth.
As it turns out, organic material, liquid water, sunlight and a large moon might not be enough to ensure an exoplanet’s habitability. It also may depend on whether enough radioactive elements are present in the planet’s core.
We’ve discovered a number of “lava planets” or “magma worlds” throughout the Milky Way. These planets are in such close proximity to their stars that their surface is literally melted into a perpetual ocean of lava.
Recently, an international team of scientists, combined data from Kepler Space Telescope and Gaia Observatory revealed is that half of the Sun-like stars in our Universe could have rocky, potentially-habitable planets.
Once a star left the gravitational embrace of its solar system, its pretty much destined to drift through interstellar space forever. Astronomers call these drifters “rogue planets” and one of them have been found recently.
Astronomers have discovered what appears to be an intact, Jupiter-size planet ( WD 1856 b ) whipping around a compact white dwarf, the remnant of a Sun-like star.
Researchers have found an Earth-size exoplanet with a pi-like 3.14-day period. Whirling around its star at some 291,000 kph, the planet’s surface temperature is estimated at around 176 degrees Celsius.
Direct images of exoplanets are pretty rare. This is the first direct image of multiple exoplanets orbiting a star similar to our Sun taken by The European Southern Observatory’s Very Large Telescope (VLT).
