  • Salty Skies on a Pink Planet, Black Holes Burp, and a Lunar Lander for Moon Base 2

    Salty Skies on a Pink Planet, Black Holes Burp, and a Lunar Lander for Moon Base 2
    Jun 19 2026
    Welcome back to Astronomy Daily! In today's episode, Anna and Avery cover six of the biggest stories in space and astronomy for Friday June nineteenth, twenty twenty-six — from a salty surprise on a mysterious pink world to a little rover completing a marathon on Mars. Story 1: JWST Reveals Salty Clouds on the 'Pink Planet' GJ504b Northwestern University astronomers have used the James Webb Space Telescope to finally crack open the spectrum of GJ504b — the so-called 'Pink Planet' 57 light-years away. The discovery, published in The Astronomical Journal on June 18, reveals an atmosphere filled with exotic chemistry and salt clouds unlike anything previously observed. At just 550°F, it's the coldest planetary-mass companion ever directly imaged. Whether it's a giant planet or a brown dwarf remains an open question, but its salty skies are a first for astronomy. Study led by Aneesh Baburaj, Northwestern University's CIERA. Story 2: Astronomers Solve the Mystery of Black Holes' Delayed Radio 'Burps' Using the NSF's Very Large Array, a team led by Kate Alexander (University of Arizona) has found that roughly 40% of all tidal disruption events — moments when a supermassive black hole shreds a passing star — produce a powerful delayed radio burst months to years after the initial flare. The study, announced June 16, also identifies a chemical fingerprint in early optical spectra that can predict which black holes are likely to produce these late-stage outbursts, giving astronomers a roadmap for long-term monitoring. Story 3: SpaceX Launches NROL-179 — the 14th NRO Proliferated Architecture Mission SpaceX launched NROL-179 from Vandenberg Space Force Base in the early hours of June 19, making it the 14th mission dedicated to building out the National Reconnaissance Office's 'proliferated architecture' — a constellation of small, resilient surveillance satellites. It was the 71st Falcon 9 launch of 2026. Mission details including satellite count and orbit remain classified. Story 4: Astrobotic Unveils Griffin-1: NASA's Moon Base II Lander Pittsburgh-based Astrobotic publicly revealed its Griffin-1 lunar lander on June 15, ahead of environmental testing at NASA's Jet Propulsion Laboratory. Designated 'Moon Base II' by NASA, Griffin-1 is a 650kg-capacity infrastructure-class lander targeting the lunar south pole region. It will carry 10 payloads from 6 nations, led by Astrolab's FLIP rover (500kg), and is scheduled to launch on a SpaceX Falcon Heavy in Q4 2026. Astrobotic has been recently acquired by Voyager Technologies. Story 5: Lucy Reveals the Life Story of Double-Lobed Asteroid Donaldjohanson Results from NASA's Lucy spacecraft's April 2025 flyby of asteroid 52246 Donaldjohanson were published in Science on June 18. The study, led by Simone Marchi (Southwest Research Institute), reveals a contact binary with a surface over 40 million years old and a younger neck (under 20 million years) built by slow-motion landslides triggered as sunlight gradually braked the asteroid's rotation from a few hours to its current 252.6-hour period. Donaldjohanson is likely a fragment of the Erigone family's parent body, destroyed ~155 million years ago. Story 6: Perseverance Rover Completes a Marathon Distance on Mars NASA's Perseverance rover has driven more than 26.2 miles (42.2 km) on Mars since landing in Jezero Crater in February 2021 — completing a marathon distance. The rover continues science operations beyond the crater's western rim, studying some of the oldest rocks in the mission's history. Perseverance is approaching Opportunity's all-time distance record of 45.16 km for a rover on another world. Mission operations are funded through at least 2028.

  • A Milky Way Fossil Unearthed, Extreme Weather on a Roasted Planet, and a Space Telescope's Last Chance

    A Milky Way Fossil Unearthed, Extreme Weather on a Roasted Planet, and a Space Telescope's Last Chance
    Jun 18 2026
    A landmark episode packed with discoveries at the cutting edge of space and astronomy. Webb and Hubble redefine a category of stellar object, JWST delivers unprecedented chemistry data from an extreme exoplanet, a 21-year-old NASA observatory faces a daring robotic rescue, a multi-telescope image reveals an ancient galactic supernova, China's Tianwen-2 zeroes in on a possible fragment of our own Moon, and astronomers detect the chemical fingerprint of a planet swallowed by its star. Story 1: Webb & Hubble Rewrite History: Terzan 5 Is a 'Bulge Fossil Fragment' Using the James Webb Space Telescope and archival data from Hubble spanning 12 years, researchers have definitively reclassified Terzan 5 — a stellar system 22,000 light-years away in Sagittarius — from a globular cluster to an entirely new class of object: a 'bulge fossil fragment.' Four distinct generations of stars have been identified within Terzan 5, formed 12.5 billion, 4.7 billion, 3.8 billion, and 2.5 billion years ago. Unlike a typical globular cluster with a single ancient stellar population, Terzan 5 repeatedly formed new stars by retaining the gas and heavy elements expelled by its own supernovae. Astronomers believe Terzan 5 is a surviving relic of the primordial clumps that merged to form the Milky Way's central bulge billions of years ago — a living fossil of galaxy formation. Results were presented at the 248th American Astronomical Society meeting and published in Astronomy & Astrophysics. Source: NASA / ESA / STScI press release, 16–17 June 2026 Story 2: JWST Catches the 'Roasted Exoplanet' HD 80606 b in the Act Astronomers using the James Webb Space Telescope's MIRI instrument have observed the extreme exoplanet HD 80606 b experiencing a temperature increase of 1,100°F (600°C) during its close approach to its host star. HD 80606 b is a gas giant four times the mass of Jupiter on a highly elliptical 111-day orbit. The JWST study — led by Tiffany Kataria of NASA's Jet Propulsion Laboratory — also detected specific atmospheric chemical signatures including methane and carbon dioxide, enabling detailed study of how the planet's chemistry shifts under extreme heating. This is the most detailed look yet at an atmospheric response to a rapid, intense heating event. Results were presented at the 248th AAS meeting in Pasadena, California. Source: NASA / JPL press release, 16–17 June 2026 Story 3: Swift's Rescue Mission Cleared for Launch: LINK on the Pad NASA's Neil Gehrels Swift Observatory, which has studied gamma-ray bursts and other high-energy cosmic events since 2004, is facing re-entry as its orbit decays under increased solar activity. NASA contracted Katalyst Space Technologies in September 2025 to build and launch a robotic servicing spacecraft — called LINK — to boost Swift to a higher orbit. LINK is now encapsulated inside a Northrop Grumman Pegasus XL rocket, which has been attached to the Stargazer L-1011 carrier aircraft and is en route to Kwajalein Atoll in the Marshall Islands for launch later in June 2026. This will be the final flight of the Pegasus XL — the world's first privately developed orbital launch vehicle, which first flew in 1990. Its air-launch capability is uniquely suited to reaching Swift's unusual low-inclination orbit. Source: NASA press release and media teleconference, 17 June 2026 Story 4: Possible Supernova Remnant at the Galactic Centre A striking multi-telescope composite image released as NASA's Astronomy Picture of the Day on 18 June 2026 reveals a possible supernova remnant near the galactic centre — a blue X-ray-emitting structure whose light is estimated to have reached Earth approximately 1,700 years ago, in the third century CE. The image combines X-ray data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton (the blue structure), radio data from the MeerKAT telescope in South Africa (the large red cloud), and optical background star data from the PanSTARRS telescopes in Hawaii. Source: NASA APOD, 18 June 2026. Image credit: NASA/CXC/UCLA/Z. Zhu et al.; ESA/XMM-Newton; MeerKAT; PanSTARRS Story 5: China's Tianwen-2 Closes In on Earth's 'Quasi-Moon' China's Tianwen-2 spacecraft — launched in May 2025 — performed its primary orbit insertion burn at asteroid 469219 Kamoʻoalewa on June 7, 2026, and has since been performing fine adjustment burns tracked by amateur radio astronomers in Germany and the Netherlands. China's space agency has released no official updates. Kamoʻoalewa is a 40–100 metre quasi-satellite of Earth, orbiting the Sun in a path that keeps it perpetually near our planet. Its reflectance spectrum resembles weathered lunar rock, fuelling a theory that it is a fragment blasted from the Moon by an ancient impact — though a competing theory holds that it is an ordinary inner asteroid belt migrant. Sample collection is scheduled to begin July 4, 2026. Tianwen-2 will depart Kamoʻoalewa in April 2027, with the sample return ...
