Former cryptocurrency company plans reality TV competition to pick next Blue Origin spaceflight crew

NeRD

A former cryptocurrency company plans to launch a reality television series that will follow its efforts to send people from underrepresented nations to space aboard a Blue Origin suborbital vehicle. The Space Exploration and Research Agency (SERA), formerly called the Crypto Space Agency, plans to send people from India, Nigeria and a region known as the Small Island Developing States on a future Blue Origin flight, the U.S. company announced Monday (July 1). Spaceflight candidates will first be chosen through a public voting system, then the finalists will participate in…

Giant river system that existed 40 million years ago discovered deep below Antarctic ice

NeRD

Geologists digging into the massive ice sheet of West Antarctica have discovered the remains of an ancient river system that once flowed for nearly a thousand miles. The discovery offers a glimpse into the Earth’s history and hints at how extreme climate change could alter the planet, according to their findings, published June 5 in the journal Science Advances.  “If we think about a potentially severe climate change in the future, we need to learn from periods in Earth’s history where this already happened,” Johann Klages, study co-author and a sedimentologist at the Alfred…

Watch SpaceX catch Starship Super Heavy booster with ‘chopsticks’ in this animation

NeRD

A new SpaceX video gives us a glimpse of the future — the very near future, perhaps. Late last week, Elon Musk‘s company posted on X a 60-second animation showing Super Heavy — the first stage of SpaceX’s giant new Starship rocket — coming back down to Earth after a liftoff.  SpaceX has made rocket landings relatively routine, commonly bringing back the first stages of its workhorse Falcon 9 and powerful Falcon Heavy vehicles. But the touchdown in the animation is different: It’s a midair catch performed by the “chopstick” arms of…

Once-in-a-lifetime star explosion, visible from Earth, could happen any day now

NeRD

If you’ve always wanted to witness a stellar explosion, your time is about to come.  T Coronae Borealis, also known as T CrB (pronounced tee-core-bore) or the “Blaze Star,” is on the precipice of a massive explosion — one that should be visible from Earth. According to calculations by Brad Schaefer, Professor Emeritus of Astronomy at Louisiana State University, along with data from amateur astronomers affiliated with the American Association of Variable Star Observers (AAVSO), the nova should occur within a few months of May 2024. T CrB is a binary…

Mars Odyssey celebrates 100,000 orbits, captures epic view of solar system’s largest volcano

NeRD

NASA’s Odyssey spacecraft, the longest-running mission at Mars, circled the Red Planet for the 100,000th time today, the mission team announced in a statement. To celebrate the milestone, the space agency released an intricate panorama of Olympus Mons, the tallest volcano in the solar system;  Odyssey captured the view in March. The volcano’s base sprawls 373 miles (600 kilometers) near the Martian equator while it soars 17 miles (27 kilometers) into the planet’s thin air. Earlier this month, astronomers discovered ephemeral morning frost coating the volcano’s top for a few…

It’s International Asteroid Day, and astronomers have much to celebrate

NeRD

Today, astronomers and space lovers around the world are collectively marveling at our mercurial presence in the universe, particularly as we drift the cosmos amid large asteroids like the one that wiped out the dinosaurs 66 million years ago. June 30 marks Asteroid Day, a holiday observed annually to reflect on the prospect of a planet-destroying space rock striking Earth and what scientists are doing to mitigate that risk. The day is observed on the anniversary of the 1908 Tunguska event in Russia, when a space rock about half the…

What are rogue planets?

NeRD

A rogue planet is a world that has been ejected from the planetary system in which it originally formed.  Because rogue planets do not orbit a parent star, they are cast adrift into interstellar space. On their meanderings, rogue planets are pulled toward whatever large, gravitationally attractive body they happen to pass by. Most rogue planets are ejected during the early stages of planetary formation when planetary systems are more chaotic and there is more interaction among planets, David Bennett, a senior research scientist at NASA’s Goddard Space Flight Center,…
