New Vera Rubin Observatory discovers 2,000 unknown asteroids within 10 hours
While about 20,000 previously unknown asteroids are discovered every year by telescopes around the world and spacecraft in orbit, the first images by the new Vera C. Rubin Observatory revealed 2,000 undiscovered asteroids taken during about 10 hours of scanning the night sky.
There are dozens of telescopes on Earth and satellites in the sky searching for new objects that might pose a threat to our planet. The National Science Foundation-Department of Energy's Vera C. Rubin Observatory in Chile was not built to be an all-in-one asteroid detector.

Still, as a fast-moving, machine-learning facility, the observatory is the most effective at spotting interstellar objects passing through the solar system, according to the NSF.
The Vera C. Rubin Observatory took two decades to complete and was named after the American astronomer credited with the first evidence of dark matter.
Later this year, work will begin creating the largest astronomical movie yet of the Southern Hemisphere, known as the Legacy Survey of Space and Time, using a camera of the same name.
The LSST Camera is the largest digital camera in the world with a field of view of about 45 times the area of the full Moon in the night sky. One image would need 400 Ultra HD TV screens to display.

A Revolutionary War-era boat is being painstakingly rebuilt after centuries buried beneath Manhattan
ALBANY, N.Y. (AP) — Workers digging at Manhattan's World Trade Center site 15 years ago made an improbable discovery: sodden timbers from a boat built during the Revolutionary War that had been buried more than two centuries earlier. Now, over 600 pieces from the 50-foot (15-meter) vessel are being painstakingly put back together at the New York State Museum . After years on the water and centuries underground, the boat is becoming a museum exhibit. Arrayed like giant puzzle pieces on the museum floor, research assistants and volunteers recently spent weeks cleaning the timbers with picks and brushes before reconstruction could even begin. Though researchers believe the ship was a gunboat built in 1775 to defend Philadelphia, they still don't know all the places it traveled to or why it ended up apparently neglected along the Manhattan shore before ending up in a landfill around the 1790s. 'The public can come and contemplate the mysteries around this ship,' said Michael Lucas, the museum's curator of historical archaeology. 'Because like anything from the past, we have pieces of information. We don't have the whole story.' From landfill to museum piece The rebuilding caps years of rescue and preservation work that began in July 2010 when a section of the boat was found 22 feet (7 meters) below street level. Curved timbers from the hull were discovered by a crew working on an underground parking facility at the World Trade Center site, near where the Twin Towers stood before the 9/11 attacks. The wood was muddy, but well preserved after centuries in the oxygen-poor earth. A previously constructed slurry wall went right through the boat, though timbers comprising about 30 feet (9 meters) of its rear and middle sections were carefully recovered. Part of the bow was recovered the next summer on the other side of the subterranean wall. The timbers were shipped more than 1,400 miles (2,253 kilometers) to Texas A&M's Center for Maritime Archaeology and Conservation. Each of the 600 pieces underwent a three-dimensional scan and spent years in preservative fluids before being placed in a giant freeze-dryer to remove moisture. Then they were wrapped in more than a mile of foam and shipped to the state museum in Albany. While the museum is 130 miles (209 kilometers) up the Hudson River from lower Manhattan, it boasts enough space to display the ship. The reconstruction work is being done in an exhibition space, so visitors can watch the weathered wooden skeleton slowly take the form of a partially reconstructed boat. Work is expected to finish around the end of the month, said Peter Fix, an associate research scientist at the Center for Maritime Archaeology and Conservation who is overseeing the rebuilding. On a recent day, Lucas took time out to talk to passing museum visitors about the vessel and how it was found. Explaining the work taking place behind him, he told one group: 'Who would have thought in a million years, 'someday, this is going to be in a museum?'' A nautical mystery remains Researchers knew they found a boat under the streets of Manhattan. But what kind? Analysis of the timbers showed they came from trees cut down in the Philadelphia area in the early 1770s, pointing to the ship being built in a yard near the city. It was probably built hastily. The wood is knotty, and timbers were fastened with iron spikes. That allowed for faster construction, though the metal corrodes over time in seawater. Researchers now hypothesize the boat was built in Philadelphia in the summer of 1775, months after the first shots of the Revolutionary War were fired at Lexington and Concord in Massachusetts. Thirteen gunboats were built that summer to protect Philadelphia from potential hostile forces coming up the Delaware River. The gunboats featured cannons pointing from their bows and could carry 30 or more men. 'They were really pushing, pushing, pushing to get these boats out there to stop any British that might start coming up the Delaware,' Fix said. Historical records indicate at least one of those 13 gunboats was later taken by the British. And there is some evidence that the boat now being restored was used by the British, including a pewter button with '52' inscribed on it. That likely came from the uniform of soldier with the British Army's 52nd Regiment of Foot, which was active in the war. It's also possible that the vessel headed south to the Caribbean, where the British redirected thousands of troops during the war. Its timbers show signs of damage from mollusks known as shipworms, which are native to warmer waters. Still, it's unclear how the boat ended up in Manhattan and why it apparently spent years partially in the water along shore. By the 1790s, it was out of commission and then covered over as part of a project to expand Manhattan farther out into the Hudson River. By that time, the mast and other parts of the Revolutionary War ship had apparently been stripped. 'It's an important piece of history,' Lucas said. 'It's also a nice artifact that you can really build a lot of stories around.' Error! Sorry, there was an error processing your request. There was a problem with the recaptcha. Please try again.

Photos show Swiss glaciers' uncertain future as ‘ambassadors of climate change'
RHONE GLACIER, Switzerland (AP) — Drip, drip. Trickle, trickle. That's the sound of water seeping from a sunbaked and slushy Swiss glacier that geoscientists are monitoring for signs of continued retreat by the majestic masses of ice under the heat of global warming. In recent years, glaciologists like Matthias Huss of the Federal Institute of Technology in Zurich, known as ETHZ, and others have turned to dramatic measures to help protect glaciers like the Rhone Glacier, which feeds into the river of the same name that runs through Switzerland and France. One of those desperate steps involves using giant sheets to cover the ice like blankets to slow the melt. Switzerland is continental Europe's glacier capital, with some 1,400 that provide drinking water, irrigation for farmland in many parts of Europe including French wine country, and hydropower that generates most of the country's electricity. The number has been dwindling. The Alpine country has already lost up to 1,000 small glaciers, and the bigger ones are increasingly at risk. Drilling into glaciers to track what's happening inside Huss hosted The Associated Press for a visit to the sprawling glacier this month, as he carried out his first monitoring mission as summer temperatures accelerate the thaw. Under normal conditions, glaciers can regenerate in the winter, but climate change is threatening that. 'I always say glaciers are the ambassadors of climate change because they can spread this message in a very understandable way,' Huss said. 'They also cause good feelings because glaciers are beautiful. We know them from our holidays.' The vast expanse of blue, gray and white ice is riddled with cracks and grooves, and Huss says his teams at the Swiss GLAMOS glacier monitoring group have spotted a new phenomenon in Switzerland: holes appearing beneath the surface that at times widen so much that the ice above collapses. Huss uses an auger to bore into the ice, sending frosty chips upward as if from a gushing fountain. It's part of a process that involves using stakes and poles to track ice loss from melting. A better understanding of glacier melt Huss monitors melting not just at the top but also from the base of glaciers. 'Normally glaciers melt from the top because of the warm air, because of their radiation from the sun. But in recent years we realized at several sites that there is a substantive melt from the bottom,' Huss said. 'If there are some channels in the ice through which air is circulating, this can excavate big holes under the ice.' The Alps were covered with ice 20,000 years ago, but no more. It's the same story elsewhere. Experts have warned that some two-thirds of the world's glaciers are set to disappear by the end of this century Huss says only humans can help save them. 'It's difficult to save this very glacier because it could only be saved — or at least made to retreat slower — by bringing down CO2 emissions,' he said. 'But everybody can contribute on their own to reduce CO2 emissions as far as possible.' 'This will not help this glacier immediately, but it will help all glaciers in the long range,' he added. 'This is the important thing that we should think of if we see this melting ice and this big retreat — that it's time to act now.' A glacier gives way, and a village is destroyed The concerns about Switzerland's glaciers intensified recently after the southwestern village of Blatten, tucked near the Birch Glacier, was largely destroyed by a slide of rock and glacier ice in May . The village had been evacuated ahead of the slide, which covered dozens of homes and buildings and left just a few rooftops visible. A review of data showed that the Birch Glacier was a rarity in that it has been advancing while most glaciers have been receding. And its advance had been increasing in recent years, to the point that it was flowing at about 10 meters (about 30 feet) per day shortly before the collapse — a rate Huss called 'completely unsustainable.' Huss said the landslide was triggered by rocks piling onto the glacier, though he also called Birch's advance a 'precursor.' The main takeaway from the Birch Glacier collapse, Huss says, is that 'unexpected things happen.' 'If you ask me, like three weeks ago, nobody would have guessed that the whole village is going to be destroyed,' he said. 'I think this is the main lesson to be learned, that we need to be prepared.' ___ AP journalist Jamey Keaten in Geneva contributed to this report. ___ The Associated Press' climate and environmental coverage receives financial support from multiple private foundations.

Science agency staff brace for HQ takeover
The Department of Housing and Urban Development is expected to announce Wednesday that it's moving into the headquarters of the National Science Foundation in Alexandria, Virginia, according to the union representing NSF employees. But as of Tuesday evening, staff at the science foundation hadn't been informed by management about their building's incoming occupants, leaving them feeling blindsided and unsure about where they're expected to work. One NSF employee said that they had 'literally zero idea' the move was coming until reports began circulating among staffers Tuesday evening. That person was granted anonymity because they fear retaliation. Advertisement Jesus Soriano, president of the union that represents NSF employees, said he was expecting a press conference Wednesday morning in the NSF lobby including HUD Secretary Scott Turner and Virginia Republican Gov. Glenn Youngkin. Soriano said he was informed about the plans by NSF employees.
