The James Webb Space Telescope is rewriting the story of the universe — from its earliest galaxies to the eventual fate of stars like our Sun. This week on Time Across the Solar System, Tess explores six remarkable discoveries across cosmic time: JWST finds unexpectedly large populations of hidden, faint stars in ancient galaxies; the Treasure Chest cluster in the Carina Nebula gets a surprising new age; galaxy cluster XLSSC 122 appears far more mature than expected; astronomers investigate a bizarre “black hole star” from only 660 million years after the Big Bang; water is detected around the dying star IRS 3 close to Sagittarius A*; and the Lion Nebula (NGC 2392) offers a glimpse of what may eventually happen to our own Sun. From stellar nurseries to dying stars, gravitational lensing and supermassive black holes, this episode asks the question at the heart of the series: how does looking across space allow us to look across time? A family-friendly journey through astronomy, astrophysics and the latest discoveries from the James Webb Space Telescope. Explore planetary time, calculators, lesson plans and more at tatssp.com.

A galaxy cluster appears to smile at us from deep space, Vesta reaches opposition and becomes easier to spot from Earth, and astronomers detect an unusual form of methanol in interstellar space for the first time. This week on Time Across the Solar System, Tess explores ten stories connected by one idea: Change the viewpoint, and the story changes. We look behind the launch pad at workforce changes supporting NASA’s Artemis programme, explore Hubble’s famous gravitationally lensed “smiley face”, meet a new small-launch startup targeting orbit in 2028, and hear what it actually feels like to work outside a spacecraft. We also follow Vesta across the night sky, view spiral galaxy NGC 1827 edge-on with Hubble, examine the International Space Station’s roll-out solar arrays, look down on West Antarctica from orbit, explore NASA’s new “Super Intelligence” terminology, and investigate the first reported detection of fully deuterated methanol around a young star. Ten stories. One big idea: The universe changes depending on how you look at it. Family-friendly astronomy, space science and planetary perspectives with Tess.

Crew-13 has arrived at the International Space Station, Crew-12 is back on Earth, and astronomers have traced a fast radio burst whose signal travelled for more than ten billion years before reaching us. This week on Time Across the Solar System, Tess explores ten stories showing that nothing in space runs on just one clock. We follow Crew-13’s rapid journey to the ISS, Crew-12’s return after seven months in orbit, and South Korea’s latest multi-satellite launch. We then travel much farther out to investigate the most distant fast radio burst yet located, a possible second-generation planet born after its star died, and a magnetic switchback traced back toward the Sun by Solar Orbiter. Mars contributes one of the strangest weather stories of the week with a morning cloud stretching roughly 1,800 kilometres, while Phobos carries the enormous Stickney Crater and continues its slow journey inward toward Mars. We also look beneath the Moon for possible lava-tube caves that could one day shelter astronauts, and beneath Antarctic ice, where the IceCube experiment detects ghostly neutrinos from some of the most energetic places in the universe. Ten stories. One big idea: Nothing in space runs on just one clock. Family-friendly astronomy, planetary science and space news with Tess.

Could a suitcase-sized spacecraft listen to the universe before the first stars existed? This week on Time Across the Solar System, Tess explores ten stories about one of astronomy’s most extraordinary rules: the farther into space we look, the further back in time we see. We meet CosmoCube, a small spacecraft designed to hide behind the Moon and listen for ancient hydrogen from the cosmic dark ages. The James Webb Space Telescope reveals a spectacular gravitational-lensing “house of mirrors”, evidence of enormous planet-shattering collisions, mysterious Little Red Dots that may contain rapidly growing black holes, and early galaxies already spreading the ingredients needed for planets and life. Closer to home, Webb explores tiny brown dwarfs in the stellar nursery IC 348, astronauts travel rapidly to the International Space Station, ESA’s JUICE spacecraft borrows momentum from Earth on its journey to Jupiter, Mars begins a new year, and SMILE starts watching the invisible magnetic shield surrounding our planet. Ten stories. One big idea: In space, looking farther away often means looking further back in time. Family-friendly astronomy, planetary science and space news with Tess.

A moon of Uranus may once have hidden an ocean more than one hundred miles deep. Astronomers have detected radio bursts coming directly from a planet sixty-three light-years away. And NASA is uncovering a much more complicated history of water on ancient Mars.This week on Time Across the Solar System, Tess explores ten stories about something astronomy does remarkably well: discovering things we cannot see directly.We investigate Ariel’s possible subsurface ocean, new techniques for tracking asteroids through their shadows, radio emissions from Beta Pictoris b, Perseverance’s evidence for complex water systems on Mars, life surviving extreme heat on Earth, and Jupiter’s unexpectedly complicated magnetic shield.We also look at Earth’s changing planetary boundaries, Hubble completing its 200,000th orbit, a newly identified giant crater on the Moon, and a white dwarf producing a shock wave that astronomers cannot yet fully explain.Ten stories. One big idea:The most important things in space are often invisible.Family-friendly astronomy, planetary science and space news with Tess.More episodes, calculators and educational resources at tatssp.com
Starship has a new launch date. Mars has turned purple. And Hubble has found a galaxy whose centre appears to be rotating in a completely different direction from the rest. This week on Time Across the Solar System, Tess explores ten stories showing how space is becoming a place humanity must not only explore, but also schedule, monitor and manage. We look at SpaceX’s next Starship flight, Europe’s growing launch market, tiny brown dwarfs photographed by the James Webb Space Telescope, the strange colours of Mars’ south pole, International Observe the Moon Night and brilliant Venus. We also examine the growing problem of satellites and debris in Earth orbit, the increasing importance of orbital infrastructure, an impact crater discovered in the Canadian wilderness, and Hubble’s remarkable view of NGC 4698. Ten stories. One big idea: Space is not empty. It is active, changing and increasingly crowded. Family-friendly space news, astronomy and planetary science with Tess.
