Can you imagine flying through space with a laser-powered rocket? It seems like something more about of science fiction than reality, right? Yet a new method for improving the thrust generated by laser-propulsion systems could bring laser-powered rockets closer to reality.
Scientists are learning a bit more about how planets form. Using the Atacama Large Millimeter/submillimeter Array (ALMA), they've detected a streamer of dust and gas flowing from a massive outer disk toward the inner reaches of a binary star system.
The sun's activity is ramping up, and now NASA's Solar Dynamics Observatory (SDO) has captured some of the images of solar flares.
NASA scientists have uncovered a starting new find on Saturn's moon, Titan. They've found an unexpected high-altitude methane ice cloud, similar to exotic clouds formed high above Earth's own poles.
On Thursday, Oct. 23, the moon passed between the Earth and the sun, causing a solar eclipse. Now, scientists have released an image of a "ring of fire" that captures this particular eclipse at its most stunning.
A pulsating star that appears to shine with the energy of 10 million stars may just be one of many in space.
Astronomers have managed to image an exploding fireball from a nova that erupted last year.
Using extremely faint light from galaxies 10.8 billion light-years away, scientists created one of the most complete, 3D maps of the early universe.
NASA's Fermi detected a rapid-fire storm of high-energy blasts from a magnetar, a highly magnetized neutron star.
Sky gazers are in luck today. A partial solar eclipse will occur across North America this Thursday during the evening hours, so make sure to catch a glimpse--as long as the weather cooperates.
Space debris is starting to be a huge problem for satellites orbiting Earth. Now, it turns out that the Suomi NPP satellite experienced a near-miss when it comes to avoiding space trash in Earth's orbit.
