The first images from the James Webb Space telescope have been revealed. Incredibly clear images of the Carina Nebula, the Eight-Burst Nebula, a galaxy cluster called Stephan’s Quintet and an exoplanet named WASP-96b make up the first set of science data from JWST.
Decades of work, $10 billion in spending and nearly 14 billion years of cosmic history have brought us to this moment. The first science from the James Webb Space Telescope, the largest and most powerful observatory ever built. What questions will it answer? What new mysteries will discover? What will this new eye on the cosmos reveal? The telescope’s first science images will be out VERY soon. Here’s a quick look at what you can expect when they drop.

The thought of finding alien life has fascinated people since the time of the ancient Greeks—but developments in astrobiology could be about to turn this possibility into reality. How do you hunt for life beyond Earth—and might this be the decade when we find it?

The Hubble Space Telescope celebrated its 32nd year in orbit by premiering a stunning new Hubble image of a collection of five galaxies, known as Hickson Compact Group 40. Even after all these years, Hubble continues to uncover the mysteries of the universe. These are a few science achievements from Hubble’s latest year in orbit.
Precisely ageing subgiant stars gives new insight into the Milky Way’s formation, and uncovering Yellowstone’s hydrothermal plumbing system.

00:45 Accurately ageing stars reveals the Milky Way’s history
To understand when, and how, the Milky Way formed, researchers need to know when its stars were born. This week, a team of astronomers have precisely aged nearly a quarter of a million stars, revealing more about the sequence of events that took place as our galaxy formed.

12:34 Uncovering Yellowstone’s hot water plumbing
Yellowstone National Park’s iconic geothermal geysers and volcanic landmarks are well studied, but very little was known about the ‘plumbing system’ that feeds these features. Now a team of researchers have mapped the underground hydrothermal system, showing the specific faults and pathways that supply the park.

19:27 Briefing Chat
We discuss some highlights from the Nature Briefing. This time, 0why an Australian university has been suspended from winning a research foundation’s fellowships, and the ongoing debate about the cause of ‘COVID toes’.
The James Webb Space Telescope, a collaboration between NASA, the European Space Agency and the Canadian Space Agency, is set to launch later this month. Scientists say its technology makes it 100 times more powerful than the Hubble and could give it the ability to see back to the first galaxies in the universe. Illustration: Adele Morgan/WSJ
The surface of Venus is completely inhospitable for life: barren, dry, crushed under an atmosphere about 90 times the pressure of Earth’s and roasted by temperatures two times hotter than an oven. But was it always that way? Could Venus once have been a twin of Earth — a habitable world with liquid water oceans? This is one of the many mysteries associated with our shrouded sister world. 27 years have passed since NASA’s Magellan mission last orbited Venus. That was NASA’s most recent mission to Earth’s sister planet, and while we have gained significant knowledge of Venus since then, there are still numerous mysteries about the planet that remain unsolved. NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) mission hopes to change that. Video credit: NASA’s Goddard Space Flight Center
For millennia, bright lights sprinkled across our celestial sphere have guided great explorers, passed on storied traditions, and lent insight into the nature of our universe. Now, they have competition: thousands of satellites circling the globe in low orbit. Read the story: https://www.science.org/content/artic…
