Spaceflight 🚀#HelioLinc3D spotted an #asteroid ☄️ that similar surveys had failed to see. It was specifically designed for the @VRubinObs in #Chile 🇨🇱. The #observatory’s huge mirror 📡, massive camera and expansive eye will see 👁️ pretty much everything in the night sky 🌌 in unprecedented detail https://www.nytimes.com/2023/08/05/science/space-asteroids-rubin-heliolinc3d.html
In 📆 2018, #StephenHawking considered an #asteroid ☄️ collision to be the biggest threat to the #planet. The #US National Science and Technology Council warned that America is unprepared for an asteroid impact 💥 event https://en.wikipedia.org/wiki/Asteroid_impact_prediction
“Our goal is that by 📆 2030, #Europe 🇪🇺 can provide early warning for hazardous #asteroids larger than 40 m in size, about three weeks before any impact” https://www.esa.int/Space_Safety/Flyeye_ESA_s_bug-eyed_asteroid_hunter

“The most glaring mistake is the #government cover-up… just completely bogus.” And a #meteorite that struck southwest #Ontario in November illustrated that a cover-up couldn’t be further from the truth when actual Earth-pummeling #asteroids ☄️ are found. https://www.sciencefocus.com/news/you-help-protect-earth-asteroid

We simply didn't notice 🙈 until recently 😨 https://ourworldindata.org/data-insights/over-33000-near-earth-asteroids-have-been-detected-since-1990
Over 40,000 near-Earth asteroids have been detected since 1990
Since the late 20th century, astronomers and space agencies have taken steps to monitor the threat of large asteroids passing near Earth. They set up international efforts to find these objects early, track their paths, and learn more about what they’re made of, so we’d have the best chance of spotting a real collision risk in time.
“We’ve taken an existing dataset… and what we realized is that there are many, many tens of thousands of #asteroids ☄️ in those datasets that nobody has noticed before. And you can unlock them if you have enough computation.” 💻 https://www.smithsonianmag.com/smart-news/scientists-discover-27500-asteroids-in-old-telescope-images-using-ai-180984277/

As of today, we have identified less than half of all near-Earth objects ☄️ at least 140 meters across. The International Astronomical Union’s Minor Planet Center has recorded 34,152 #asteroids with orbits that come within 0.05 AU of the Earth 🌍. Starting in 📆 2025, #NEO searches will get a big boost when the @VRubinObs 🔭 finally achieves first light. https://arstechnica.com/science/2024/05/outdoing-the-dinosaurs-what-we-could-do-if-we-spot-a-threatening-asteroid/
The largest camera 📷 ever built for #astronomy, the 3.2-gigapixel Legacy Survey of Space and Time CCD camera will capture the night sky 🌌 above the southern hemisphere 1,000 times each night in six wavelengths, from ultraviolet to near-infrared, totaling 15 terabytes. It’s likely to catalog 90% of near-Earth objects, such as #asteroids ☄️, larger than 300 meters 📏 —and calculate if they are a threat to Earth. https://www.forbes.com/sites/jamiecartereurope/2024/04/30/this-is-what-the-worlds-biggest-and-best-new-digital-camera-will-image-in-32-gigapixels/

“It would have been great to detect the object ☄️ prior to colliding with the Earth,” said Juan Luis Cano, a member of the #PlanetaryDefence Office at the #ESA https://www.nytimes.com/2024/05/19/science/comet-fireball-portugal-spain.html

Near-Earth objects (NEOs) represent potentially catastrophic threats to our planet. The approximate total impact energy of the #Chelyabinsk Fireball 2013 was 440 kilotons, the most energetic impact 💥 event recognized since the 1908 #Tunguska blast in Russian Siberia. https://www.un.org/en/observances/asteroid-day
#Comet A3 ☄️ can now also be seen in the northern hemisphere, @royalastrosoc said.
Between 12 and 30 October, people may be able to see the comet using binoculars or even with the naked eye 👀 https://www.independent.co.uk/space/comet-a3-century-neanderthals-skies-tonight-b2628266.html
