A mysteriously dimming star located about 1,480 light-years away in the constellation of Cygnus and known as Tabby's star is, in fact, a binary stellar system, made up of a F-type star and a smaller red dwarf star.
Kraken Mare, a sea of liquid methane on Saturn's moon Titan, is at least 100-m deep near its center, according to a recent analysis of Cassini's data.
The Juno spacecraft orbiting Jupiter has discovered an FM radio signal coming from the moon Ganymede. The find is a first-time detection from the moon. The signal is of natural origin.
Blue Origin says it is “very, very close” to flying humans on suborbital launches to the edge of space after a successful test flight of a human-capable rocket and capsule last Thursday.
The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn.
Only 31 magnetars ( type of neutron star that has the strongest magnetic field ) have even been discovered and recently astronomers have found an extremely unique object that is both a magnetar and a pulsar.
A submarine mission to Saturn’s largest moon has long been under discussion. If such a mission was ever launched, it would have plenty of room to operate, because Titan’s largest sea, Kraken Mare, is likely more than 300 m deep.
Since 2019, NASA's InSight's probe, called the “mole,” has been attempting to burrow into the Martian surface. Martian soil’s tendency to clump deprived the mole of the friction it needs to hammer itself to a sufficient depth.
The current tilt of Saturn's rotation axis is caused by the migration of its satellites, and especially by that of its largest moon, Titan. Titan and the other moons are moving away from Saturn much faster than it had been previously estimated.
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.
It is thought that the upper mass limit for galactic black holes is around 100 billion solar masses, but new research suggests the mass limit could be much higher - more than a million times greater than the largest galactic black holes.
Thursday evening SpaceX's Falcon 9 rocket was successfully launched for the 50th time. It has only been five years and a few days since they landed their first one.
Astronomers are studying black holes that could have formed in the early universe, before stars and galaxies were born. Such primordial black holes (PBHs) could account for all or part of dark matter.
Three to four billion years ago, Mars did in fact have running rivers of water. Now, scientists have mapped out an entire ancient river system.
Astronomers using NASA's Hubble Space Telescope watched a mysterious dark vortex on Neptune (a storm, which is wider than the Atlantic Ocean) abruptly steer away from a likely death on the giant blue planet.
