The spectacular Perseid meteor shower, peaking Thursday night (Aug. 11–12), lights up Earth’s sky every summer as Earth passes through the trail left by Comet Swift-Tuttle, a miles-wide behemoth that swings by Earth every 133 years.
You don’t have to know a whole lot about science to know that black holes typically suck things in, not spew things out. But NASA just spotted something mighty strange at the supermassive black hole Markarian 335.
Unusual X-ray emissions coming from four old red dwarf stars suggest these old fogeys have something in common with our sun: their magnetic fields are weakening over time, new research shows.
Delicate space nets. Probes landing with the force of a bomb. Ice-burrowing tunnellers. These are a few of the robots poised to grab the baton from NASA’s Cassini orbiter in the search for alien life on Saturn’s icy moon Enceladus.
In the tens of thousands of photos returned by NASA’s Dawn spacecraft, the interior of Ceres isn’t visible. But scientists have powerful data to study Ceres’ inner structure: Dawn’s own motion.
Jupiter’s volcanic moon Io has a thin atmosphere that collapses in the shadow of Jupiter, condensing as ice, according to a new study by NASA-funded researchers. The study reveals the freezing effects of Jupiter’s shadow during daily eclipses on the moon’s volcanic gases.
Space is beautiful. These are nine images of the most beautiful sights we have of space that people have taken pictures of.
Detailed analysis of data collected by Rosetta show that comets are the ancient leftovers of early Solar System formation, and not younger fragments resulting from subsequent collisions between other, larger bodies. Understanding how and when objects like Comet 67P/Churyumov-Gerasimenko took shape is of utmost importance in determining how exactly they can be used to interpret
There is a mystery afoot surrounding the craters, or lack thereof, on Ceres, our nearest dwarf planet that resides within the asteroid belt between the orbits of Mars and Jupiter in our solar system.
Indian astronomers have recently conducted spectrographic observations of long-period Comet Lovejoy to study its gas emission. They found that this comet showcases an asymmetric behavior at perihelion and an increase in the activity during the post-perihelion phase.
