This artist’s concept shows one of NASA’s Voyager spacecraft entering interstellar space, or the space between stars. This region is dominated by plasma ejected by the death of giant stars millions of years ago. Hotter, sparser plasma fills the environment inside our solar bubble.

For the second time in history, a human-made object has reached the space between the stars. NASA’s Voyager 2 probe now has exited the heliosphere – the protective bubble of particles and magnetic fields created by the Sun. Comparing data from different instruments aboard the trailblazing spacecraft, mission scientists determined the probe crossed the outer edge of […]
New observations by three of the world’s largest radio telescopes have revealed that an asteroid discovered last year is actually two objects, each about 3,000 feet (900 meters) in size, orbiting each other. Near-Earth asteroid 2017 YE5 was discovered with observations provided by the Morocco Oukaimeden Sky Survey on Dec. 21, 2017, but no details […]
Using observations from NASA’s Hubble Space Telescope and ground-based observatories, an international team of scientists have confirmed ‘Oumuamua (oh-MOO-ah-MOO-ah), the first known interstellar object to travel through our solar system, got an unexpected boost in speed and shift in trajectory as it passed through the inner solar system last year. “Our high-precision measurements of ‘Oumuamua’s […]
