Space dominated this week’s science news, with NASA announcing its imminent next steps in plans to develop a permanent moon base being slightly overshadowed by the spectacular explosion of a rocket intended to carry its payloads.
Three uncrewed missions targeted for later this year will involve private companies carrying payloads to the lunar surface ahead of astronauts’ return by 2028. Nonetheless, some experts have voiced skepticism about NASA’s highly ambitious timeline, with the gigantic detonation of Blue Origin’s New Glenn rocket during a static “hotfire” test likely prompting significant delays.
If that’s not exotic enough for you, we reported on the far-out mystery of the controversial “JuMBO” planets discovered by the James Webb telescope, alongside the telescope’s discovery of a “naked” black hole that’s heavier than its host galaxy.
But you don’t need to go to space to find new ways of looking at the universe, as you can see in this fascinating interview on the uses of radio astronomy in space exploration and the search for aliens. Indeed, you can gain that sense of awe by watching this new footage of a brilliant-green fireball meteor exploding over an erupting volcano in the Philippines.
Hybrid quantum computer AI can solve questions base models can’t

Today’s artificial intelligence (AI) chatbots are notoriously prone to getting things wrong.
To get more accurate, large language models historically (LLM) had to get bigger, using ever more parameters and thus gobbling up more compute time. Now, however, scientists have found a way around this seemingly inevitable tradeoff — and they did it by inserting a quantum computing component into the AI.

The result led to a small reduction in the perplexity score — used to quantify the inaccuracies LLMs make in predicting their next tokens — and an improvement in the questions the hybrid AI could answer compared with a base model.

Jet lag is a mismatch between our internal body clock and our time zone.

If you’ve taken a long-haul flight before, you’re likely well aware of what jet lag feels like — the enervating feeling of temporal discombobulation that lingers for days after hopping into a new timezone. But what’s going on in our bodies to cause it? And can it be prevented?

“Doomsday Glacier” will lose ice shelf
Thwaites Glacier has been melting rapidly since the 1980s.

Antarctica’s Thwaites Glacier is nicknamed the “Doomsday Glacier” because its collapse would raise global sea levels by 2.1 feet (65 centimeters) and flood coastal communities worldwide.
This week, we reported that a key shelf buttressing the glacier is set to fall apart this year.
It sounds depressing, but that doesn’t necessarily spell immediate doom. While scientists can’t put an exact timeline on Thwaites Glacier’s collapse, they don’t think it will be anytime soon. That at least gives people living in cities such as New York, Boston, and Miami a little time to consider moving inland.

Science Spotlight
War is deepening a water crisis in Iran that has depleted the country’s surface water, as well as its groundwater resources.

The U.S.-Israeli war has come at a price measured not just in military expenditures but in human lives, key infrastructure and rising energy prices.
But some costs of the war aren’t immediately apparent. One of the less-publicized tolls, for example, is the effect on Iran’s water system, which was already collapsing before the current war. In this Science Spotlight, Live Science staff writer Sascha Pare walks us through how the water crisis originated, how the war made things worse, and whether the situation can be turned around.

This stunning photo of the Whirlpool Galaxy could reveal clues to how stars form.

This snapshot of the bruised-blue Martian surface was taken by NASA’s Psyche spacecraft as it passed within 2,864 miles (4,609 kilometers) of the Martian surface on May 15.
The image — a close-up of the double-ringed Huygens crater and the cratered southern highlands that surround it — was captured by the probe to test its multispectral cameras before it arrives at the metal-rich asteroid 16 Psyche in 2029. The enhanced-color processing in the photos revealed veins of hidden mineral deposits, hence the blue.
