    Did a Planetary Society citizen scientist help find one of Earth’s biggest impact craters? About 66 million years ago, a 10-kilometer-wide hunk of rock smashed into Earth near what is now Mexico's Yucatán Peninsula.The impact created a global dust cloud that snuffed out the sunlight, leading to the demise of 80 percent of Earth's plants and animals—including most of the dinosaurs. A 200-kilometer-wide crater buried near the city of Chicxulub is all that's left. It's ground zero for one of the world's most notable extinction events.But throughout Earth's history, there have actually been five major extinction events. The largest of...

    NASA has announced that it has discovered 10 new “potentially hazardous” space rocks close to Earth that could put life on this planet at risk. The space agency has been working tirelessly to identify dangers that Earth face from space, and has said that it has found 10 new asteroids or meteors which it believes could harm life on Earth. The discovery was made by NASA’s asteroid detecting mission – Near-Earth Object Wide-field Infrared Survey Explorer or NEOWISE.

    Yet another Jovian fireball? On May 26th, amateur astronomers recorded a rare impact flash in Jupiter's north polar region. Jupiter just got beaned for the sixth time (that we know about)! On the evening of May 26th, between 19:24.6 and 19:26.2 Universal Time, Sauveur Pedranghelu, a French amateur from Corsica, detected an impact flash live on video in Jupiter's north polar region. The flash was very brief, lasting only about 0.7 second, and displayed two brightness peaks. A bright dot — about the size of Europa when seen in transit — marked the site of impact at latitude 51° north...

    Psyche, NASA's Discovery Mission to a unique metal asteroid, has been moved up one year with launch in the summer of 2022, and with a planned arrival at the main belt asteroid in 2026 -- four years earlier than the original timeline. “We challenged the mission design team to explore if an earlier launch date could provide a more efficient trajectory to the asteroid Psyche, and they came through in a big way,” said Jim Green, director of the Planetary Science Division at NASA Headquarters in Washington. “This will enable us to fulfill our science objectives sooner and at a...

    2017 HX4 passed us by at a very safe distance. In fact, the asteroid’s closest approach to Earth was estimated to be at a distance of 3.7 Lunar Distances (LD) – i.e. almost four times the distance between the Earth and the Moon. This, and other pertinent information was tweeted in advance by the International Astronomical Union’s Minor Planet Center (IAU MPC) on April 29th. This object was first spotted on April 26th, 2017, using the 1.8 meter Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), located at the summit of Haleakala in Hawaii. Since that time, it has been...

    A relatively large asteroid will cross Earth's orbit around the sun this month. Astrophysicists and astronomers say there is no chance of a collision, but it will be the closest flyby of an asteroid that large for at least another 10 years. Asteroid 2014 JO25, discovered three years ago, is about 650 meters (2,100 feet) in diameter, 60 times as large as the small asteroid that plunged into our atmosphere as a meteor and exploded over the Russian city of Chelyabinsk in 2013. That blast was felt thousands of kilometers away and caused havoc on the ground, damaging more than...
  • Asteroid to Fly Safely Past Earth on April 19 (Asteroid 2014 JO25, Diameter = 2,000 feet)

    NASA ^ | 4/6/17
    A relatively large near-Earth asteroid discovered nearly three years ago will fly safely past Earth on April 19 at a distance of about 1.1 million miles (1.8 million kilometers), or about 4.6 times the distance from Earth to the moon. Although there is no possibility for the asteroid to collide with our planet, this will be a very close approach for an asteroid of this size. The asteroid, known as 2014 JO25, was discovered in May 2014 by astronomers at the Catalina Sky Survey near Tucson, Arizona -- a project of NASA's NEO Observations Program in collaboration with the University...

    Less than 10 feet across, asteroid 2017 EA made its closest approach at 9:04 AM EST (14:04 Universal Time) last Thursday, coming 20 times closer than the Moon, just 9,000 miles (14,500 km) over the eastern Pacific Ocean, according to a NASA statement. The space agency’s Center for Near-Earth Object Studies (CNEOS), which operates out of the Jet Propulsion Laboratory (JPL) in California, tracks asteroids and comets that come close to the Earth and computes very precise orbits for them but did not detect this asteroid until just six hours before its closest approach to Earth. It was first sighted...

    o radar imager Lance Benner at JPL in Pasadena, asteroid 2017 BQ6 resembles the polygonal dice used in Dungeons and Dragons. But my eyes see something closer to a stepping stone or paver you’d use to build a walkway. However you picture it, this asteroid is more angular than most imaged by radar. It flew harmlessly by Earth on Feb. 7 at 1:36 a.m. EST (6:36 UT) at about 6.6 times the distance between Earth and the moon or some about 1.6 million miles. Based on 2017 BQ6’s brightness, astronomers estimate the hurtling boulder about 660 feet (200 meters) across....

    Monday at 7:47 A.M. EST, an asteroid passed by Earth at about half the distance between our planet and the Moon—roughly 119,500 miles, reports Mike Wall at Space.com. The space rock, dubbed 2017 AG13 was on the "smallish" size as far as asteroids go, Wall reports, thought to be between 36 and 111 feet wide. But the most interesting thing about this near miss is that astronomers didn't spot the space rock till Saturday. It managed to fly under the radar for so long because the asteroid was fairly dim and moving fast (roughly ten miles per second). But just...

    An asteroid roughly the size of a 10-story building gave Earth a particularly close pass Monday morning. Asteroid 2017 AG13 came within half the distance from Earth to the moon as it buzzed by early Monday morning at 4:47 a.m. PT. The fly-by happened shortly after scientists at the Catalina Sky Survey first discovered the space rock on Saturday. ... In the cosmic sense, it really was a close shave. In real terms, Earth had well over a 100,000-mile (161,000 kilometer) buffer of distance. ... The asteroid is about 36 to 111 feet (11 to 34 meters) across, according to...

    The American space agency says that one object is a massive comet, but has so far been unable to identify the other NASA recently spotted two massive space objects hurtling towards Earth. While the American space agency has pinpointed one as a comet, the other has left it slightly more baffled. The comet is set to fly close to Earth this week, but the mystery object isn't expected to make an appearance until February. The object, dubbed "2016 WF9", was detected by NASA's asteroid- and comet-hunting NEOWISE project on 27 November 2016. It is roughly 0.3 to 0.6 miles (0.5...

    CAPE CANAVERAL, Fla. (Reuters) - A U.S. space probe was cleared for launch on Thursday to collect and return samples from an asteroid in hopes of learning more about the origins of life on Earth and perhaps elsewhere in the solar system, NASA said on Tuesday. A United Launch Alliance Atlas 5 rocket was scheduled to blast off from Cape Canaveral Air Force Station in Florida to dispatch the robot explorer Osiris-Rex on a seven-year mission. United Launch Alliance is a partnership of Lockheed-Martin and Boeing. Osiris-Rex is headed to a 1,640-foot (500-meter) wide asteroid named Bennu, which circles the...

    On Saturday, astronomers discovered a new asteroid, just a few hours before it almost hit us. The asteroid is called 2016 QA2, and it missed the Earth by less than a quarter of the distance to the moon. That puts it about three times as far away from Earth as our farthest satellites. And we never saw it coming. So how did 2016 QA2 sneak up on us like that? For this particular asteroid, the answer seems to be that it has a very peculiar orbit. It's highly elliptical, which means it can usually be found hanging out by either...

    Paging Bruce Willis! NASA is planning to launch a probe to study an asteroid that could one day pulverize the Earth. The asteroid, named Bennu, crosses Earth’s orbit once every six years and has gotten ever closer since it was discovered in 1999, astronomers told the Sunday Times of London (paywall). In 2135, Bennu will fly between the moon and Earth — a hair’s breadth in space terms, the Times reported. That’s so close that gravity from the Earth could effect Bennu’s orbit, “potentially putting it on course for the Earth later that century,” said Dante Lauretta, a professor of...

    Phobos and Deimos are both small for moons — about 14 and 7.7 miles (22.5 and 12.4 kilometers) wide, respectively — and sort of potato-shaped. Compared to other satellites in the solar system, they look more like asteroids. As a result, astronomers previously hypothesized that these moons were asteroids captured by Mars' gravitational pull. ...previous research suggested that Phobos and Deimos would have relatively irregular orbits. In reality, these moons have nearly circular orbits positioned near the Martian equator. ... huge impact that previous research suggested created the gigantic Borealis basin in the northern lowlands of Mars, which covers two-fifths...

    A volcano on Mars half the size of France spewed so much lava 3.5 billion years ago that the weight displaced the Red Planet's outer layers, according to a study released Wednesday. Mars' original north and south poles, in other words, are no longer where they once were. The findings explain the unexpected location of dry river beds and underground reservoirs of water ice, as well as other Martian mysteries that have long perplexed scientists, the lead researcher told AFP. "If a similar shift happened on Earth, Paris would be in the Polar Circle," said Sylvain Bouley, a geomorphologist at...
