Read previewIn the search for intelligent alien life, finding a Dyson sphere would be like hitting the jackpot. Dyson spheres are a hypothetical, super-advanced form of alien technology that may surround seven stars in our galaxy. Love Employee/Getty ImagesDespite what the name suggests, a Dyson sphere isn't necessarily one solid sphere that encases a star, although the most advanced ones could be. AdvertisementFor their study, Majumdar and colleagues analyzed more than 5 million stars throughout the Milky Way that exhibit IEEs. Next, the researchers will look closer at these seven strong Dyson sphere candidates using spectroscopic analysis, Majumdar said.

For a night at the symphony, there was a lot of tension in the air. The evening’s program was just the sort of thing he had promised when he was hired with a mandate to rethink the concert experience: Ravel’s charming “Mother Goose” brought to life by dancers from Alonzo King’s LINES Ballet, and then Schoenberg’s nightmarish “Erwartung” staged by the director Peter Sellars. His decision to leave once his contract is up next year has upset fans — “Who he is and what he brings can’t be replicated,” Mark Malaspina, an audience member, lamented as he entered the hall — and left some concerned about the future of the 113-year-old San Francisco Symphony. “An orchestra that was in very good shape is now in crisis,” said Peter Pastreich, a longtime arts administrator who managed the San Francisco Symphony from 1978 to 1999. “It is heartbreaking to watch.”

☆ Dyson spheres: Could alien megastructures exist in the Milky Way? Scientists found 7 places to look

Now, a new study that looked at 5 million stars in the Milky Way galaxy suggests that seven candidates could potentially be hosting Dyson spheres — a finding that’s attracting scrutiny and alternate theories. If Dyson spheres really exist, what could they be used for? “Freeman Dyson said that we should dismantle Jupiter — the whole planet (for the raw materials).”That supercolossal scale probably means that Dyson spheres, if they exist at all, are very rare. “However, contamination by circumstellar debris disks, which mimic Dyson Sphere infrared signatures, remains a concern,” he added in an email. However, he added, the radiation fingerprint of the seven Dyson sphere candidates might be explained by natural phenomena as well.

“Based on rough estimates, it’s about 150,000 metric tons of water ice, the equivalent of 60 Olympic swimming pools,” he said. The volcanoes are near the Mars equator, the warmest area of the planet, which makes a water discovery particularly intriguing, Valantinas said. “Mars is a desert planet, but there’s water ice in the polar caps, and there’s water ice in the midlatitudes. Now we also have water frost in the equatorial regions, and equatorial regions are quite dry in general. “If the frost on these volcanoes is confirmed to be water (and not carbon dioxide), it would be surprising,” he said.

☆ A 'cosmic glitch' in the universe is forcing astronomers to rethink Einstein's theory of relativity
▼ + stars: | 2024-05-20 | by ( Ellyn Lapointe | ) www.businessinsider.com time to read: +8 min

Einstein's general theory of relativity states that the curvature of space-time causes gravity. But zoom out to enormous scales like clusters of galaxies spanning billions of light years across, and the laws of Einstein's gravity theory appear to change. A 1% adjustment may not sound like a big deal, but it's enough to suggest that Einstein's theory may need a rethink. Now, with this cosmic glitch, there's a new explanation on the table. NASA/CXC/Univ of Missouri/M.Brodwin et al; NASA/STScI; JPL/CalTechThe fact that this cosmic glitch could potentially help astronomers resolve the Hubble tension is a good sign that it may truly exist.

But the kicker is that this giant void shouldn't exist in the first place. For example, some people have correctly argued that such a void shouldn't exist in the standard model, which is true. Cosmologists have a value, called the Hubble constant, which they use to help describe how fast the universe's expansion is accelerating. The Hubble constant should be the same value wherever you look, whether it's close by or very far away. NASA/JPL-CaltechAstronomers can't agree on what's causing this discrepancy in the Hubble constant, and the contention has become known as the Hubble tension.

Over the past few years, states like Ohio and Arkansas have expanded their school voucher programs to allow most or all parents to receive funding to send their kids to private schools.

This incident serves as an example of the urgent need for a profound shift toward sustainable space practices. Proponents of a circular space economy advocate for a transformative departure from this wasteful paradigm. Much like embracing reusable materials on Earth, transitioning to a circular space economy means designing space systems with reuse, refurbishment and recyclability in mind. The European Space Agency (ESA) has emerged as a trailblazer in the pursuit of a circular space economy. By leading the charge toward sustainable space practices, NASA can inspire other space agencies and private companies to follow suit.

Observations from the European Space Agency’s Cheops space telescope, or Characterising ExOplanet Satellite, detected a “glory effect” on WASP-76b, an ultra-hot exoplanet 637 light-years from Earth. Cheops captured data from WASP-76b as the planet passed in front of its star, making 23 observations over three years. But the glory effect is created as light moves through a narrow opening and bends, creating colorful, patterned rings. An artist's illustration shows the night-side view of the exoplanet WASP-76b, where iron rains down from the sky.

Garbage disposal in spaceNASA routinely brings home batches of science experiments, cargo and garbage from the space station using capsules such as the Dragon spacecraft built by SpaceX. But after the installation of new batteries on the space station in 2021, authorities disposed of a pallet of aging nickel-hydrogen batteries in a different way. But the debris that struck Otero’s house was the result of miscalculations about how space garbage would behave.

CNN —Astronomers using the James Webb Space Telescope have detected commonplace chemical ingredients found in vinegar, ant stings and even margaritas around two young stars, according to NASA. The complex organic molecules they observed using the space observatory’s Mid-Infrared Instrument included acetic acid, a component of vinegar, and ethanol — otherwise known as alcohol. The team also found simple molecules of formic acid, which causes the burning sensation associated with ant stings, as well as sulfur dioxide, methane and formaldehyde. Stars form from swirling clouds of gas and dust, and the leftover material from star formation gives rise to planets. Detecting complex organic molecules in space is helping astronomers to determine the molecules’ origins as well as those of other larger cosmic molecules.

But in October at Davies Symphony Hall, the home of the San Francisco Symphony, the piece was being prepared with an additional sense in mind. Onstage, the pianist Jean-Yves Thibaudet practiced his solo part in “Prometheus,” which the San Francisco Symphony will perform March 1 through 3, while the conductor Esa-Pekka Salonen listened attentively to the wooden vortexes as they were being tested; the sound they made while emitting smoke, he noticed, was nearly a G.Mathilde Laurent, Cartier’s longtime perfumer, who had designed the scents, double-checked notes on her iPad.

CNN —A European Space Agency satellite is expected to reenter and largely burn up in Earth’s atmosphere on Wednesday morning. The agency’s Space Debris Office, along with an international surveillance network, is monitoring and tracking the Earth-observing ERS-2 satellite, which is predicted to make its reentry at 6:14 a.m. The exact time of the satellite’s reentry remains unclear due to the unpredictability of solar activity, which can change the density of Earth’s atmosphere and how the atmosphere tugs on the satellite. The ERS-2 satellite has an estimated mass of 5,057 pounds (2,294 kilograms) after depleting its fuel, making it similar in size to other space debris that reenters Earth’s atmosphere every week or so, according to the agency. ERS-2’s backstoryThe Earth-observing ERS-2 satellite first launched on April 21, 1995, and it was the most sophisticated satellite of its kind at the time to be developed and launched by Europe.
