New images recorded by NASA’s Parker Solar Probe have revealed the red-hot glow of Venus‘s surface radiating through its shroud of toxic clouds – a finding that could help us better understand the minerals making up this rocky and mysterious planet. Using data from the Wide-field Imager for Parker Solar Probe (WISPR) instrument, scientists … Read more
Black holes may be well known for their gluttonous tendencies, but they’re not the only dead stars capable of slurping down passing objects. For years, evidence has been mounting that white dwarf stars also have a penchant for snacking – and on their own planets, no less. Now, for the first time, astronomers have … Read more
The Perseverance rover’s self-driving function is working just great on Mars, according to NASA’s Jet Propulsion Laboratory. The mission, not quite at one Earth year on Mars, has topped a new distance record for Red Planet rovers. On Friday (Feb. 4) Perseverance made the longest drive completed in a single Martian day, or sol, traveling … Read more
The dust storm couldn’t keep NASA’s Mars helicopter Ingenuity grounded forever. The 4-pound (1.8 kilograms) Ingenuity aced a 100-second sortie on Tuesday (Feb. 8), its 19th Red Planet flight overall but its first since Dec. 15. The flight had originally been targeted for Jan. 5. But on New Year’s Day, a big dust storm kicked … Read more
At a point some 12,800 years ago, a tenth of Earth’s surface suddenly became covered in roaring fires. The firestorm rivalled the one that wiped out the dinosaurs, and it was likely caused by fragments of a comet that would have measured around 100 kilometers (62 miles) across. As dust clouds smothered Earth, they … Read more
When young stars coalesce out of a cloud of molecular hydrogen, a disk of leftover material called a protoplanetary disk surrounds them. This disk is where planets form, and astronomers are getting better at peering into those veiled environments and watching embryonic worlds take shape. But young stars aren’t the only stars with disks of … Read more
Jupiter’s auroras – the lights that dance around its poles – are the most distinct in our solar system and over a thousand times brighter than Earth’s aurora. Now, a new study confirms that these otherworldly polar lights come from a unique source: space lava. Jupiter‘s moon Io is the most volcanically active world in the solar … Read more
The climate crisis enveloping Earth impacts the lowest depths of the sea and the most remote parts of the planet. And new research shows that it’s also causing change at the highest points of the world. Scientists studying South Col – Mount Everest’s highest glacier – have reported that rapid ice loss is occurring … Read more
The distance to Mars from Earth varies considerably depending on their orbits around the sun. In theory, the closest Mars and Earth would get is when Mars reaches its closest point to the sun (perihelion) and Earth is at its farthest (aphelion). This would bring the two planets within 33.9 million miles (54.6 million kilometers) … Read more
