MUSE data reveals hydrogen reservoirs around earliest galaxies

MUSE data reveals hydrogen reservoirs around earliest galaxies

Science
Oct. 1 (UPI) -- Astronomers have discovered an abundance of Lyman-alpha radiation in Hubble Ultra-Deep Field. The data -- collected by the MUSE spectrograph on ESO's Very Large Telescope -- suggests the universe's earliest galaxies were surrounded by large reservoirs of hydrogen. The Hubble Ultra-Deep Field is a small, dark region of the night sky home to a large concentration of ancient galaxies. The field is home to thousands of the cosmos' earliest galaxies, as they appeared just a few hundred million years after the Big Bang. The field's light spent 12 billion years traveling to Hubble's lens. Lyman-alpha emission, or radiation, is the spectral line of hydrogen. As revealed by the spectrographic data collected by MUSE, the early universe was saturated by Lyman-alpha emission. "Realiz...
Watch live: Elon Musk to announce first private passenger to fly around the moon

Watch live: Elon Musk to announce first private passenger to fly around the moon

Science
Sept. 17 (UPI) -- SpaceX founder Elon Musk is set to announce the first private space passenger to fly around the moon on Monday evening. Musk's announcement will be streamed live online. Coverage begins at 9 p.m. ET. According to SpaceX, the mystery passenger will be carried on a trip around around the moon on the aerospace company's next-generation rocket, the Big Falcon Rocket, or BFR. The plans aren't exactly new. In 2017, SpaceX said two unnamed people had put down large deposits to reserve a spot on the private lunar flight. Originally, the Falcon Heavy -- which completed its first static test fire earlier this year -- was scheduled to carry space tourists to the moon and back. Those plans were nixed. Now, if all goes as planned, passengers will by ferried by BFR. As The Verge repo...
SpaceX changes plans to send tourists around the moon

SpaceX changes plans to send tourists around the moon

Technology
SpaceX said it has signed the first private moon traveler, with some changes to its original game plan. The big reveal on who it is — and when the flight to the moon will be — will be announced Monday at the company's headquarters in Hawthorne, California. It's not the same mission SpaceX founder Elon Musk outlined last year. The original plan called for two paying passengers to fly around the moon this year, using a Falcon Heavy rocket and a Dragon crew capsule. At the time, Musk said the pair approached SpaceX about sending them on a weeklong flight and paid a "significant" deposit for the trip. The new strategy is to still fly around the moon, but using an even bigger SpaceX rocket still in development that has its own dedicated passenger ship. And now, it appears there wi...

Apple co-founder Steve Wozniak says the hype around blockchain signals a bubble

Finance
Apple co-founder and noted bitcoin bull Steve Wozniak says the hype around blockchain is similar to what he saw in the dotcom era, with companies going belly-up at a rapid rate. “It was a bubble, and I feel that way about blockchain,” Wozniak said Tuesday on stage at the NEX technology conference in New York. A good portion of the companies promising to do life-changing things on the internet quickly went bust, Wozniak reminded the audience. Still, he said blockchain technology has real implementation potential, because it’s “decentralized a...
