Six Planets Tonight — And a Galaxy-Sized Mystery Solved ⭐ Feb 26, 2026

Show notes

Astronomy Daily | S05E49 | February 26, 2026 Six Planets, a Surprise in the Milky Way, and the First ISS Medical Evacuation Revealed Tonight the Moon sits right next to Jupiter in what is the visual highlight of the February six-planet alignment. Meanwhile, astronomers have made a jaw-dropping discovery about our galaxy’s magnetic field, NASA has named the astronaut at the centre of last month’s historic ISS medical evacuation, and a hypersonic scramjet launch has been scrubbed. All that and more in today’s episode. IN THIS EPISODE • SKYWATCHING — Moon-Jupiter conjunction tonight: the six-planet alignment (Mercury, Venus, Jupiter, Saturn, Uranus, Neptune) is peaking right now, with Jupiter blazing beside the waxing Moon after sunset. The Blood Moon total lunar eclipse arrives March 3. • DEEP SPACE — The world’s largest radio telescope array has made new chemical discoveries in the turbulent heart of the Milky Way around Sagittarius A*, our galaxy’s supermassive black hole. • ARTEMIS UPDATE — NASA’s SLS rocket has returned to the Vehicle Assembly Building for repairs; early April is now the earliest realistic launch window for the crewed lunar flyby. • ISS — NASA has named the astronaut who required the first-ever medical evacuation from the International Space Station, following last month’s early return of Crew-11. • SCIENCE — A groundbreaking new map of the Milky Way’s magnetic field reveals an unexpected diagonal reversal in the Sagittarius Arm — a discovery that prompted an OMG moment for the lead researcher. • LAUNCH UPDATE — Rocket Lab’s HASTE ‘That’s Not a Knife’ hypersonic mission carrying an Australian hydrogen scramjet demonstrator has been scrubbed; no new date yet.

Slow Crawl, Fast Comet Feb 24, 2026

Show notes

Today on Astronomy Daily: NASA's Artemis II mission is rolling back to the Vehicle Assembly Building today after a helium flow issue dashed hopes of a March launch. We cover the latest on what went wrong, what it means for the April window, and what happens next. We also have five more stories to get through: Perseverance just gained the ability to locate itself on Mars with GPS-like precision — no Earth assistance required. Scientists have published a daring plan to intercept interstellar comet 3I/ATLAS using a solar slingshot manoeuvre, with a launch in 2035 and a 50-year journey to follow. China's mysterious Shenlong space plane is back in orbit on its fourth mission, and we still know almost nothing about it. We run through this week's packed launch schedule — including Rocket Lab's hypersonic scramjet test flight happening today, and Firefly Aerospace's return to flight on Friday. And we close with a genuinely beautiful piece of science: researchers have used supercomputers to solve a 50-year-old mystery about how elements move inside red giant stars.

Countdown to the Moon: Artemis II Crew in Quarantine Feb 21, 2026

Show notes

Astronomy Daily — Season 5, Episode 45 | February 21, 2026 "Countdown to the Moon: Artemis II Crew in Quarantine" The Artemis II crew — Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch (NASA), and Mission Specialist Jeremy Hansen (CSA) — have officially entered quarantine ahead of a targeted March 6, 2026 launch. With the second Wet Dress Rehearsal completed successfully on February 19th, humanity is just two weeks away from returning to the Moon for the first time since Apollo 17 in 1972. Anna and Avery break down everything you need to know about this historic mission. Also on today's episode: • DARK MATTER UNDER PRESSURE: A new paper in Physical Review D claims its findings represent the first step toward the end of dark matter theory as we know it — researchers have found a plethora of baryonic (ordinary) dark matter signals that challenge the standard cosmological model. • AURORA WATCH: A large coronal hole on the Sun has rotated into a geoeffective position, with fast solar wind expected to reach Earth around February 22nd. Skywatchers at higher latitudes should keep their eyes on the skies tomorrow night. • MARS WATER UPDATE: New research suggests water ice on Mars may be accessible far closer to the equator than previously believed — a game-changing development for future human exploration of the Red Planet. • SERIAL KILLER BLACK HOLES: Astronomers using James Webb Space Telescope data have confirmed that active supermassive black holes don't just shut down star formation in their own galaxies — they can suppress star formation in neighbouring galaxies too. • SPACEX NEAR MISS: SpaceX successfully landed its Falcon 9 booster in The Bahamas for only the second time ever after launching 29 Starlink satellites — but someone at SpaceX admitted they 'almost did have a really terrible day.'

Moon Hides Mercury Tonight, Artemis II Tests Tomorrow, Saturn Ring Origin Revealed Feb 18, 2026

Show notes

Episode: S05E42 — Wednesday, February 18, 2026 Hosts: Anna & Avery Network: Bitesz.com Podcast Network In today's episode of Astronomy Daily, Anna and Avery cover six unmissable stories from across the cosmos. Here's what we're talking about in S05E42: 1. Artemis II Wet Dress Rehearsal Round Two NASA begins fuelling the SLS moon rocket tomorrow (Feb 19) for a second critical practice countdown. Engineers have replaced two seals and a filter after hydrogen leaks forced the February launch window to be abandoned. A clean test is required before NASA will commit to a launch date — currently no earlier than March 6. The four-person crew includes Victor Glover, Christina Koch, and Jeremy Hansen, each of whom will make history on the flight. 2. Moon Occults Mercury Tonight — Plus a Ganymede Transit Tonight, February 18, a thin crescent Moon passes so close to Mercury that observers in Arizona, New Mexico, Texas, Louisiana, Mississippi, and Georgia will see the Moon hide Mercury in a rare occultation. For everyone else, a stunning close conjunction is visible in the western sky just after sunset. Simultaneously, Jupiter's moon Ganymede transits the gas giant's face through the night. Two events, one evening. 3. Ariane 6 Launches Amazon Kuiper Satellites Europe's most powerful Ariane 6 configuration successfully launched 32 satellites for Amazon's Project Kuiper broadband constellation today — a direct competitor to SpaceX's Starlink. The launch highlights both the commercial ambitions of Amazon's internet satellite programme and the ongoing resurgence of European launch capability. 4. 3I/ATLAS Update: JUICE Data Downlinking Now ESA's JUICE spacecraft is currently transmitting data it collected on interstellar comet 3I/ATLAS back to Earth — the downlink window runs February 18–20. If successful, this would be the closest-ever spacecraft observations of an interstellar object. Meanwhile, 3I/ATLAS heads toward a close Jupiter flyby in March that may trigger fresh outbursts. 5. How Titan Formed — And Why Saturn Has Rings New research from the SETI Institute proposes a single ancient catastrophe that explains multiple Saturn mysteries at once: a moon called proto-Hyperion collided with proto-Titan about 400 million years ago. The merger debris re-accreted into Saturn's inner moons and left behind the iconic ring system. The hypothesis also explains Saturn's unusual axial tilt, Iapetus's orbital inclination, and the surprising youth of Titan's surface. 6. Russia's 30-Day Mars Engine Rosatom's Troitsk Institute is ground-testing a nuclear-powered magnetoplasma engine that its developers claim could reach Mars in 30 days — compared to 8 months for chemical rockets. With a plasma exhaust velocity of 100 km/s, the system is part of a global race toward deep-space plasma propulsion also being pursued by NASA's VASIMR programme and Chinese researchers. A flight prototype is targeted for 2030.
