World’s largest International Dark Sky Reserve created

April 8, 20221109 Views

McDonald Observatory, Community Partners come together to form 15,000 sq miles reserve The world’s largest International Dark Sky Reserve is coming to Texas and Mexico, thanks to a partnership between The University of Texas at Austin’s McDonald Observatory, The Nature Conservancy, the International Dark-Sky Association (IDA) and many others. The designation, granted by the IDA, recognizes the commitment of organizations, governments, businesses and residents in the region to maintaining dark skies. The move will benefit not only astronomical research, but also wildlife, ecology and tourism. The new Greater Big Bend International Dark Sky Reserve will encompass more than 15,000 square miles in portions of western Texas and northern Mexico. It is the only such reserve to cross an int...

Offers clues about the primordial universe An international team of astronomers, including researchers at the Center for Astrophysics | Harvard & Smithsonian, has spotted the most distant astronomical object ever: a galaxy. Named HD1, the galaxy candidate is some 13.5 billion light-years away and is described in the Astrophysical Journal. In an accompanying paper published in the Monthly Notices of the Royal Astronomical Society Letters, scientists have begun to speculate exactly what the galaxy is. The team proposes two ideas: HD1 may be forming stars at an astounding rate and is possibly even home to Population III stars, the universe’s very first stars — which, until now, have never been observed. Alternatively, HD1 may contain a supermassive black hole about 100 million t...

The International Space Station (ISS) is set to become busier than usual this week when its crew welcomes aboard four new colleagues from Houston-based startup Axiom Space, the first all-private astronaut team ever flown to the orbiting outpost. The launch is being hailed by the company, NASA and other industry players as a turning point in the latest expansion of commercial space ventures collectively referred to by insiders as the low-Earth orbit economy, or "LEO economy" for short.

Successfully lands after taking six on a 10-minute suborbital voyage Blue Origin, the space tourism venture launched by entrepreneur Jeff Bezos, completed its fourth flight with a crew on Thursday, landing successfully in rural west Texas after taking a half dozen passengers for a 10-minute suborbital joyride. The New Shepard spacecraft blasted off at 8:59 a.m. CDT (1359 GMT), and the crew capsule separated from the six-story-tall rocket a short time later as it soared to an altitude of 66 miles (106 km). University of North Carolina professor Jim Kitchen shows a flag with "194" written on it, symbolizing his visits to 193 countries on Earth and his trip to sub-orbital space, as he emerges from the capsule of Blue Origin's rocket New Shepard after landing near Van Horn, Texas, U....

Towering ice volcanoes identified on surprisingly vibrant Pluto

Could hint towards possibility of life on the dwarf planet A batch of dome-shaped ice volcanoes that look unlike anything else known in our solar system and may still be active have been identified on Pluto using data from NASA's New Horizons spacecraft, showing that this remote frigid world is more dynamic than previously known. Scientists said on Tuesday that these cryovolcanoes - numbering perhaps 10 or more - stand anywhere from six-tenths of a mile (1 km) to 4-1/2 miles (7 km) tall. Unlike Earth volcanoes that spew gases and molten rock, this dwarf planet's cryovolcanoes extrude large amounts of ice - apparently frozen water rather than some other frozen material - that may have the consistency of toothpaste, they said. A heart shaped region named Sputnik Planum is seen in a...

Delayed for two days because of poor weather conditions The fourth commercial flight of Jeff Bezos’ space tourism venture Blue Origin, offering short suborbital joyrides to well-heeled thrill-seekers and celebrity guests, has been delayed by two days because of poor weather conditions, the company said. Blue Origin’s New Shepard spacecraft was scheduled for liftoff on Tuesday from the company’s launch site in rural west Texas at 8:30 a.m. CDT (1330 GMT) with six would-be citizen astronauts strapped into the crew cabin atop the fully autonomous launch vehicle, standing nearly six stories tall.

Jeff Bezos' Blue Origin space tourism service has postponed until March 29 a flight initially set for next week, while "Saturday Night Live" comic Pete Davidson will not be a passenger on the launch, the company has said. The company, in a brief notice first posted on Twitter, gave no immediate explanation for the change or Davidson's withdrawal from the manifest of Blue Origin's fourth commercial flight since last summer. Davidson, 28, the boyfriend of reality TV star and socialite Kim Kardashian, had just been officially named on Monday as Blue Origin's "honorary guest" to join five paying customers on the flight initially set for March 23. With "Davidson no longer able to join" the new flight, Blue Origin said it would announce the sixth crew member "in the coming days." ...

Stellar ‘vampire’ finds love at first bite with companion star

“Closest black hole” system found to contain no black hole Astronomers have gotten a good look at what happens when a "vampire" star sucks the outer layers of material from a companion star, stripping this "bitten" victim down to a mere stellar core. In 2020 a team led by European Southern Observatory (ESO) astronomers reported the closest black hole to Earth, located just 1000 light-years away in the HR 6819 system. But the results of their study were contested by other researchers, including by an international team based at KU Leuven, Belgium. In a paper published on Wednesday, these two teams have united to report that there is in fact no black hole in HR 6819, which is instead a “vampire” two-star system in a rare and short-lived stage of its evolution. The original study on...

NSF’s NOIRLab in Chile captures stunning image through Dark Energy Camera Located in the constellation Dorado and lying around 70 million light-years away, NGC 1566 is a grand-design spiral galaxy with two arms that appear to wind around the galactic core, just like the arms of a dancer as they spin around and around in a furious twirl. This image was taken from Chile at the Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF’s NOIRLab, using the Dark Energy Camera. The galaxy's face-on view to us, its location, and its composition make it a trove of observational opportunities for astronomers across many fields of astronomy. This image, taken by astronomers using the US Department of Energy-fabricated Dark Energy Camera on the Víctor M. Blanco 4-meter Telescope at Cerr...
