A star that sounds as if it came from “The Lord of the Rings” now marks one of the Hubble Space Telescope’s farthest frontiers: The fuzzy point of light, known as Earendel, has been dated to a mere 900 million years after the Big Bang and appears to represent the farthest-out individual star seen to date.
Based on its redshift value of 6.2, Earendel’s light has taken 12.9 billion years to reach Earth, astronomers report in this week’s issue of the journal Nature. That distance mark outshines Hubble’s previous record-holder for a single star, which registered a redshift of 1.5 and is thought to have existed when the universe was 4 billion years old.
The newly reported record comes with caveats. First of all, we’re talking here about a single star rather than star clusters or galaxies. Hubble has seen agglomerations of stars that go back farther in time.
“Normally at these distances, entire galaxies look like small smudges, with the light from millions of stars blending together,” lead author Brian Welch, an astronomer at Johns Hopkins University, said today in a news release. “The galaxy hosting this star has been magnified and distorted by gravitational lensing into a long crescent that we named the Sunrise Arc.”
A close look at the arc turned up several bright spots, but the characteristics of the light coming from Earendel pointed to a high redshift, which translates into extreme distance. The higher the redshift, the faster the source of the light is receding from us in an ever-more-quickly expanding universe.
SpaceX CEO Elon Musk delivered a long-awaited, live-streamed update on his plans for launching the world’s most powerful rocket, with the spotlighted backdrop of a freshly stacked Starship and Super Heavy booster standing on the launch pad at the company’s Starbase facility in South Texas.
The Starship project is key to Musk’s plans to send thousands of settlers to Mars and make humanity a multiplanet species. It’s also key to his plans to put thousands of satellites in Earth orbit for SpaceX’s Starlink broadband network, which is supposed to bring in the money needed for Mars missions.
And as if all that’s not enough, Musk expects Starship to revolutionize space travel and society in ways that can’t be foreseen. “When you have an utterly profound breakthrough, the use cases will be hard to imagine,” he told hundreds of attendees during the Feb. 10 presentation at the Boca Chica base.
Musk exhibited his trademark optimism about the launch system’s development schedule, saying that the Federal Aviation Administration could give its go-ahead for the first Starship orbital launch from Texas as soon as next month. But he said there was a Plan B in case that approval didn’t come soon.
NASA says it plans to plunge the vestiges of the International Space Station into a remote part of the Pacific Ocean known as Point Nemo in early 2031, after passing the baton to commercial space stations.
In an updated transition report just delivered to Congress, the space agency detailed the endgame for the space station, which has been hosting international crews continuously since the year 2000 — and hinted at what its astronauts would be doing in low Earth orbit after its fiery destruction.
“The private sector is technically and financially capable of developing and operating commercial low-Earth-orbit destinations, with NASA’s assistance,” Phil McAlister, NASA’s director of commercial space, said in a news release. “We look forward to sharing our lessons learned and operations experience with the private sector to help them develop safe, reliable, and cost-effective destinations in space.”
The production company that’s playing a key role in a space movie project involving Tom Cruise says it’s working with Axiom Space to add a sports and entertainment facility to the International Space Station by the end of 2024.
The facility would provide a studio for film, TV and music production as well as a space for performances and sports events. “SEE-1 is an incredible opportunity for humanity to move into a different realm and start an exciting new chapter in space,” said SEE’s co-founders, Dmitry and Elena Lesnevsky.
Japanese billionaire Yusaku Maezawa and two crewmates have returned to Earth after an 11-day mission to the International Space Station that was marked by online innovations including an NFT drop and a lottery giveaway.
Maezawa, his production assistant Yozo Hirano, and Russian cosmonaut Alexander Misurkin took a 3.5-hour ride from the station on a Soyuz craft, climaxing in a touchdown amid the steppes of Kazakhstan around the appointed time of 0313 GMT (9:13 a.m. local time) Dec. 20.
After the landing, the three spacefliers were helped out of the capsule and given medical checks.
The short-duration stay was the first private astronaut trip to the space station brokered by Virginia-based Space Adventures in 12 years. In an interview with The Associated Press, Maezawa said reports that he paid more than $80 million for the adventure were “pretty much” accurate.
“Once you are in space, you realize how much it is worth it by having this amazing experience,” he told AP. “And I believe that this amazing experience will lead to something else.”
Even though Texas-based Axiom Space hasn’t yet sent its first crew of customers to the International Space Station, NASA is giving the company an opportunity to send a second crew, potentially just months later.
NASA says it will begin negotiations with Axiom on a space station mission scheduled sometime between the autumn of 2022 and the late spring of 2023. Under a pricing policy laid out earlier this year, NASA would charge $10 million to support each private astronaut during their stay in orbit, plus extra charges for food and supplies.
It’ll cost tens of millions more for the ride to the space station and back. The three customers who have signed up for Axiom’s first space station mission in February are reportedly paying $55 million each, which includes the fare for a trip in SpaceX’s Crew Dragon capsule.
Maezawa, production assistant Yozo Hirano and Russian cosmonaut Alexander Misurkin rode a Soyuz capsule into orbit from Russia’s Baikonur Cosmodrome in Kazakhstan, with launch coming at 0738 GMT December 8 (12:38 p.m. local time, 2:38 a.m. EST).
Hours later, the Soyuz docked with the station, and the trio floated inside to meet the orbital outpost’s seven other spacefliers. Maezawa was all smiles as he greeted family and friends back on Earth over a video link.
Before liftoff, the 46-year-old entrepreneur and art collector said he was looking forward to his journey.
“I feel excited like an elementary student waiting for a school trip,” he said at a news conference. “I want to see the Earth from space, float in zero gravity, and see how I will change through this experience. I was blessed with this opportunity, and I’m truly happy I can go.”
The science adviser for “Don’t Look Up,” a star-studded comedy about a killer comet, has some serious advice for dodging a threat from the skies: Take the title of the movie, and do the exact opposite.
“The sensible thing to do about this particular problem is … just go look up and see if it’s out there,” said Amy Mainzer, a planetary scientist at the University of Arizona’s Lunar and Planetary Laboratory. “And do a thorough enough job of it that we have a reasonable chance of spotting something that’s large enough to cause appreciable damage, well before it could make its way here.”
The roughly 5-mile-wide comet that’s heading for Earth in “Don’t Look Up,” with only about six and a half months of advance warning, is totally fictional. Nevertheless, the movie is a teachable moment for the science surrounding asteroids, comets and planetary defense. And Mainzer said the stars of the show, including Leonardo DiCaprio and Jennifer Lawrence, were unusually eager students.
“These actors wanted to know everything,” she said. “I would say they’re approaching some pretty solid knowledge of just how do we find asteroids and comets, and what do we do about them.”
Mainzer discusses what’s going on with the search for potentially threatening near-Earth objects, as well as her experience as a science adviser for “Don’t Look Up,” in the latest episode of the Fiction Science podcast, coming to you from the place where science and technology intersect with fiction and popular culture.
A wellness coach from Antigua and her daughter are getting tickets for a suborbital space trip, thanks to the latest in a line of out-of-this-world sweepstakes going back 20 years. And although not a single spaceflight sweepstakes winner has flown yet, there’s still significant value to such contests, financially and otherwise.
“Being able to give people of all ages and backgrounds equal access to space, and in turn, the opportunity to lead and inspire others back on Earth, is what Virgin Galactic has been building towards for the past two decades,” Virgin Galactic’s billionaire founder, Richard Branson, said in a Nov. 24 news release.
Branson himself broke the good news to Keisha Schahaff at her home on the Caribbean island of Antigua. Schahaff had entered a contest arranged in collaboration with the Omaze online sweepstakes platform and a nonprofit group called Space for Humanity this summer. She ended up winning the random drawing. Her grand prize? Two tickets for a ride on Virgin Galactic’s SpaceShipTwo Unity rocket plane, plus terrestrial travel expenses.
SpaceX CEO Elon Musk has laid out a scenario for space travel that calls for his company’s Starship launch system to take on its first orbital test flight as soon as January.
Starship could go through “a dozen launches next year, maybe more,” and be ready to send valuable payloads to the moon, Mars and even the solar system’s outer planets by 2023, Musk said during a Nov. 17 online meeting of the National Academies’ Space Studies Board and Board on Physics and Astronomy.
But he advised against sending anything too valuable on the first flight to Mars. “I would recommend putting the lower-cost scientific mission stuff on the first mission,” he said, half-jokingly.
The National Academies presentation followed up on big-picture talks that Musk delivered in 2016 (when Starship was known as the Interplanetary Transport System), 2017 (when it was known as the BFR or “Big Frickin’ Rocket”) and 2018 (when Musk settled on “Starship”).
Musk’s basic concept is the same: Starship and its giant Super Heavy booster would be a one-size-fits-all system that could be used for point-to-point suborbital travel, orbital space missions and all manner of trips beyond Earth orbit, including moon landings. It’d be capable of lofting more than 100 tons to low Earth orbit (three times as much as the space shuttle), and sending 100 people at a time to Mars.
This week’s presentation provided some new details.
