The Breakthrough Starshot Initiative's purpose goes far beyond the Moon. The project seeks to travel to the nearest stars.
A NASA instrument built to help astronomers learn about the structure and behavior of neutron stars has been mounted to the International Space Station.
Did our sun have a twin when it was born 4.5 billion years ago? Almost certainly yes -- though not an identical twin.
Two teams of researchers reported they have detected a prebiotic molecule—a potential building block of life—around newly formed sunlike stars.
Astronomers have confirmed the existence of the seventh planet around the ultracool dwarf star TRAPPIST-1.
Tabby's star is dipping drastically in brightness, giving astronomers an opportunity to figure out what has been causing this star's weird behavior.
Imagine being caught in the clutches of a black hole, being whirled around at dizzying speeds and having your mass slowly but continually sucked away. That’s the life of a white dwarf star that is doing an orbital dance with a black hole.
A team of scientists reports that it has discovered the existence of a white dwarf star whose atmosphere is rich in carbon and nitrogen, oxygen and hydrogen. The white dwarf is approximately 200 light years from Earth and is located in the constellation Boötes.
Mark your calendars: In 2022, a rare "red nova" will appear in the sky, according to an unprecedented and ultra-precise stellar prediction.
Although there are no seasons in space, this cosmic vista invokes thoughts of a frosty winter landscape. It is, in fact, a region called NGC 6357 where radiation from hot, young stars is energizing the cooler gas in the cloud that surrounds them.
A rare triple-star system surrounded by a disk with a spiral structure has been discovered by a University of Oklahoma-led research team.
A star with the unassuming name of KIC 8462852 in the constellation Cygnus has been raising eyebrows both in and outside of the scientific community for the past year.
As far as stars go, these two are rather close together to have such massive, Jupiter-sized planets orbiting them. The planets and their stars were found 154 light-years away in the constellation Libra.
New stars are formed in the undulating clouds of M8, also commonly referred to as the Lagoon Nebula, situated some 5,000 light years from our planet.
Scientists are preparing to unveil a new planet in our galactic neighborhood which is "believed to be Earth-like" and orbits its star at a distance that could favor life. The exoplanet orbits a well-investigated star called Proxima Centauri, part of the Alpha Centauri star system.
