When it comes to searching for asteroids, we have a blind spot. It may seem counterintuitive, but the asteroid’s most important discoveries are now being made at dusk, when astronomers can see up close to the horizon – and close to the sun – for what little is known. asteroids orbiting within the orbits of Earth, Venus and even Mercury. In perspective published in Science today, asteroid hunter Scott Sheppard of the Carnegie Institution of Science highlights the new “twilight telescope” surveys and the riches they are beginning to discover. It includes the first asteroid with an interior orbit to Venus and the one with the shortest known orbital period around the sun, both of which have been unearthed in the past two years. It also includes “city killers”, asteroids large enough that if they hit Earth the damage will be severe. “We’re doing a full survey looking for anything moving around the orbit of Venus, which is somewhere we haven’t surveyed very deeply in the past with anyth

It’s nice to know that someone actually gets paid to watch the night sky to make sure that at least we’ll be notified if an asteroid is about to hit Earth. Technology and near-Earth surveys have advanced enough that the possibility of an asteroid the size of a planet-killer appearing out of nowhere, as is so prevalent in modern media depictions, is highly unlikely. Even the smaller ones, which would only annihilate a city or part of a continent, received enough attention to know whether they posed a threat or not. And ahead of Asteroid Day 2022, which happens on June 30, the ESA is proud to announce that they can remove one of the most threatening asteroids from their list of potential impacts. The asteroid, known as 2021 QM1, was first detected at the Mount Lemmon observatory on August 28, 2021. It was only one of about a dozen near-Earth asteroids discovered that night and did not initially raise any alarm. But follow-up observations put it on a potentially near-miss path with Earth

Like corn kernels popping in a frying pan, tiny dust grains can jump up and down the asteroid’s surface, according to a new study from physicists at the University of Colorado Boulder. That popcorn-like effect could even help tidy up smaller asteroids, causing them to lose dust and look rough and craggy from space. The researchers published their results July 11 in the journal Natural Astronomy . Their findings could help scientists better understand how asteroids change shape over time – and how these objects migrate through space, sometimes bringing them very close to Earth, said Hsiang-Wen (Sean) Hsu, lead author of the study. the. “The more fine-grained material, or regolith, these asteroids lost, the faster they migrated,” said Hsu, a research associate in the Laboratory for Atmospheric and Space Physics (LASP) at CU Boulder. The research started with some curious photos. In 2020, a NASA spacecraft called OSIRIS-REx traveled more than 1 billion miles to meet the asteroid (191055)

A newly discovered star, now called S4716, is moving at 5,000 miles (8,000 km) per second around the black hole at the center of our galaxy, the Milky Way, space.com reported. The vast expanse of our universe means that astronomers are always discovering something they’ve never seen before. Earlier this week, astronomers spotted two asteroids the size of a bus heading for Earth, which will pass just a quarter of the distance that separates the Moon from us. In addition to asteroids, our galaxy is also attracting the attention of astronomers looking for signs of other planets that support life. Right at the center of the Milky Way, there is a supermassive black hole dubbed Sagittarius A* or Sgr A* and S4716 orbits this black hole at high speed. What we know about S4716 From observations made so far, we know that at 5,000 miles (8,000 km) per second or 18 million miles (29 million km) per hour, S4716 is the fastest star orbiting Sgr A*. It completes an orbit around a black hole with

A massive asteroid the size of BUS will make a very close approach to Earth today – and astronomers only detected it three DAYS ago The asteroid, called 2022 NF, is between 5.4 and 12 meters in diameter It will come within 54,843.9 miles of our planet at approximately 2:45 p.m. BST Experts only found the asteroid on July 4th using a telescope in Hawaii By Shivali Best For Mailonline Published: 05:38 EDT, 7 July 2022 | Updated: 05:39 EDT, 7 July 2022 An asteroid the size of the London bus will make a very close approach to Earth today, although it was only detected a few days ago. The asteroid, called 2022 NF, will be within 54,843.9 miles of our planet at approximately 2:45 p.m. BST, according to NASA. To put it in perspective, that’s just over a quarter of the distance from the Moon at its closest point to Earth, which is 225,623 miles away. Fortunately, NASA’s calculations suggest that the massive space rock will sa
