Ganymede is Jupiter’s largest moon; in fact it’s the solar system’s biggest moon. Now members of the Icy Worlds team at NASA’s Jet Propulsion Laboratory (JPL) think that the giant moon, which is even larger than the planet Mercury, may have several layers of ice and liquid oceans piled atop each other, much like a […]
The coldest-ever brown dwarf star has been found about 7 light-years away from Earth and could help scientist learn more about the atmospheres of planets. Brown dwarfs are objects that are too big to be planets, but too small to be considered stars. They begin their lives like stars, but since their mass is so […]
A new device developed by NASA will help planetary scientists take advantage of high altitude research balloons, a relatively inexpensive observational platform that has long been used by other scientists. The balloons, which can climb to the edge of space, have been utilized by researchers across multiple scientific disciplines, helping them to make groundbreaking findings. […]
Scientists have found signs of water vapor on the dwarf planet known as Ceres. “This is the first time water vapor has been unequivocally detected on Ceres or any other object in the asteroid belt and provides proof that Ceres has an icy surface and an atmosphere,” said Michael Küppers of the European Space Agency. […]
While in space and orbiting the sun this celestial body is an asteroid. It’s a meteor as its entering earth’s atmosphere, like a fireball flashing across the sky and a meteorite is the actual object that made it to Earth.
Astronomers have found that one of two recently-discovered moons of Jupiter is just two kilometers in diameter and may be the smallest of Jupiter’s 67 satellites. Back in September 2010, scientists discovered two unknown distant satellites of Jupiter while conducting routine tracking observations of the planet’s previously identified moons. To confirm that these were indeed […]
First, the good news. There are fewer asteroids near Earth than previously estimated. Now the bad news. A new NASA survey also finds there may be more than twice as many aligned with Earth’s orbit than thought, which could increase the odds of an asteroid coming close enough to us to cause concern. The findings […]
