This Powerful Telescope Quickly Found 1,200 New Asteroids
More than a million asteroids, some of them potential threats to Earth. Asteroids with tails like comets. Interstellar objects that happen to be swinging by our sun. (Could they be alien spaceships?) More distant worlds including, perhaps, a ninth planet, which could fill in the story of our solar system's turbulent youth.
Those are some of the discoveries that the Vera C. Rubin Observatory in Chile is expected to make in the cosmic neighborhood that is our solar system. (Maybe not the alien spaceships.)
'I think that we're going to completely transform our view of the solar system and rewrite that textbook over the next few years.' said Meg Schwamb, a planetary scientist at Queen's University Belfast in Northern Ireland.
Rubin's scans of the night sky will also help make Earth a safer place, spotting potentially dangerous asteroids that have so far eluded detection.
Most asteroids are found in the belt between the orbits of Mars and Jupiter. But some of those space rocks have been deflected onto paths that could cross paths with our planet.
Astronomers are certain that there is nothing the size of the six-mile-wide asteroid that killed the dinosaurs that poses a danger of colliding with Earth anytime soon. But for smaller asteroids, they are not so certain.

Trump Snubbed Jared Isaacman as NASA Chief, but the Private Astronaut Isn't Done With Space Yet
Although Jared Isaacman is out of the running for the position of NASA administrator, the space enthusiast is still very much interested in staying in the game. In a recent appearance, Isaacman revealed he would still like to pursue launching robotic missions to space. This weekend, Isaacman received the National Space Society's Wernher von Braun Award for the privately funded Polaris Dawn mission that he led in September 2024. After his speech, Isaacman spoke of plans he would have executed as NASA administrator, as well as some that the private astronaut is still interested in pursuing outside of the agency, SpaceNews reported. This comes less than a month after President Donald Trump withdrew his nomination of Isaacman to lead NASA in a surprising switch-up that left members of the space community disappointed. In comments to the press, Isaacman mentioned that one of the goals he had for NASA was to partner with academic organizations on science missions. 'My priorities would have been leadership in space and the orbital economy and trying to introduce a concept where NASA could help enable others to conduct interesting scientific missions, getting academic organizations to contribute,' he said. 'I wouldn't mind maybe trying to put that to a test and see if you could fund an interesting robotic mission, just to show that it can be done, and try and get some of the top tier academic institutions who want to perform,' Isaacman added. 'So that's on my mind.' Isaacman previously funded the private missions he was a part of. In 2021, he purchased all four seats on board SpaceX's Dragon spacecraft for the Inspiration4 mission. Under the Polaris Dawn program, Isaacman contracted with SpaceX to fund a series of missions, the first of which launched on September 10, 2024 and pulled off the first commercial spacewalk in history. Rather than focusing on human-led private missions, Isaacman is now looking to launch space exploration missions out of pocket. This comes at a time when NASA is facing severe budget cuts that threaten several science missions and put the agency's ability to pursue space exploration at risk. The current administration's so-called skinny budget proposes a $6 billion cut to the agency, 24% less than NASA's current $24.8 billion budget for 2025. As part of the proposal, the agency's astrophysics budget will drop to less than half a billion dollars from $1.5 billion. Its planetary science budget would drop from $2.7 billion to $1.9 billion, while its Earth science budget would fall to just over $1 billion from about $2.2 billion. NASA's Mars Sample Return, a bold quest to bring bits of Mars to Earth, is on the chopping block as part of the 2026 proposed budget. Other missions, such as NASA's Juno that has been exploring Jupiter since 2016, face cancellation, while planned future missions, such as DAVINCI and VERITAS, may never launch. Isaacman's nomination to lead NASA was a welcomed move by the space community as the agency struggles with pressure to return humans to the Moon and land astronauts on Mars. If he were given the helm, Isaacman would have focused on reusable hardware to launch the Artemis missions to the Moon while ditching NASA's Space Launch System (SLS), a giant, expendable rocket that has gone $6 billion over-budget, he revealed in a podcast earlier this month.

Vera Rubin Observatory reveals jaw-dropping first images from world's largest telescope
This morning, the world's largest telescope revealed its first-ever images of space—and they're pretty jaw-dropping. The images come courtesy of the NSF–DOE Vera C. Rubin Observatory, a scientific facility funded by the U.S. National Science Foundation and the U.S. Department of Energy's Office of Science. Located at the summit of Cerro Pachón in Chile, the facility is the product of more than 20 years of work. Its space camera—embedded in the hulking Large Synoptic Survey Telescope (LSST) —is about the size of a small car and includes a sensor array of three billion pixels, the most sensors ever used in a telescope camera. According to a press release from the Rubin Observatory, it's expected to generate an 'ultrawide, ultra-high-definition time-lapse record of the Universe.' 'It will bring the sky to life with a treasure trove of billions of scientific discoveries,' the release reads. 'The images will reveal asteroids and comets, pulsating stars, supernova explosions, far-off galaxies and perhaps cosmic phenomena that no one has seen before.' 'The most efficient Solar System discovery machine ever built' In just its first 10-hour test observation, unveiled today, the LSST managed to capture images which include millions of galaxies and Milky Way stars, as well as more than 2,000 never-before-seen asteroids within our Solar System. Taken together, the photos illustrate a technicolor view of space at a mind-boggling scale—but the 10 million galaxies photographed by the LSST represent only 0.05% of the roughly 20 billion galaxies that the camera is expected to record within the next decade. The primary goal of the LSST is to complete a 10-year survey of the Southern hemisphere sky, capturing hundreds of images and around 20 terabytes of data per night throughout that period. Per the Rubin Observatory, this massive influx of data will make the LSST 'the most efficient and effective Solar System discovery machine ever built.' All of the captured data will be made available online, allowing astronomers across the globe to access countless new findings without physical access to the telescope. The LSST is designed to advance four main areas of study: Understanding the nature of dark matter and dark energy; creating an inventory of the Solar System; mapping the Milky Way; and exploring the transient optical sky, i.e. studying objects that move or change in brightness. Experts predict that, given its capacity to identify millions of unseen asteroids, comets, and interstellar objects, the camera could even help protect the planet by spotting objects on a trajectory toward the Earth or Moon. 'NSF–DOE Rubin Observatory will capture more information about our Universe than all optical telescopes throughout history combined,' Brian Stone, chief of staff at the National Science Foundation, said in a press release. 'Through this remarkable scientific facility, we will explore many cosmic mysteries, including the dark matter and dark energy that permeate the Universe.'

TNB Tech Minute: Main Street Banks Could Get Opening to Join Stablecoin Market - Tech News Briefing
Full Transcript This transcript was prepared by a transcription service. This version may not be in its final form and may be updated. Speaker 1: Here's your TNB Tech minute for Monday, June 23rd. I'm Victoria Craig for the Wall Street Journal. Main Street banks worried about getting left behind by the push into crypto might soon get an opening. The Journal exclusively reports that financial technology giant Fiserv has plans to launch a stablecoin and platform that can be used by clients including 3,000 regional and community banks. A broad shift to crypto would put deposits at those more local banks at risk, because they're reliant on those deposits to make loans. If customers were to pull deposits and put the funds into stablecoins, it would leave those banks less room to lend and squeeze a critical revenue source. Elsewhere, German auto parts company Continental said today it's partnering with semiconductor maker GlobalFoundries to design its own vehicle computer chips. The new organization called Advanced Electronics & Semiconductor Solutions will design and test chips tailored for automotive products of its spinoff, Aumovio. Continental said the new unit will reduce geopolitical risk and make the company more self-reliant. And finally, a US-funded space observatory perched in the Andes mountains in Chile released its first images of deep space using the world's largest digital camera. It's the first time a telescope has been able to peer this far and wide into the cosmos. And for the next 10 years, the observatory will take photos of the southern sky at 30-second intervals every three to four nights. Scientists hope the project called The Legacy Survey of Space and Time will inventory the solar system, map the Milky Way, catalog billions of transient space objects, and unlock the mysteries of dark matter and energy. For a deeper dive into what's happening in tech, check out Tuesday's Tech News Briefing podcast.
