Discovery of the Week

Earth may have made its own oceans — New research suggests our planet's water didn't arrive via comet or asteroid impacts but instead was generated internally through chemical reactions in the early Earth's mantle. This "homegrown" hypothesis challenges decades of thinking about where our oceans came from. (Quanta Magazine)

Space Missions & Astronomy

• Japan's H3 rocket returns to flight — The H3 rocket launched successfully on June 11, carrying six small satellites to orbit in its first mission since a failure in December 2024. _Significance: High._ (SpaceNews)
• SpaceX shares surge nearly 20% in historic IPO — The company went public in a milestone event for the broader space industry, with shares rising sharply on the first trading day. _Significance: High._ (SpaceNews)
• NASA's Deep Space Network "worked well" on Artemis II — After nearly breaking under strain, the network of giant radio antennas that communicates with distant spacecraft performed reliably during the recent Artemis II mission. _Significance: Medium._ (Ars Technica Science)
• ESA astronaut assigned to Artemis 3 as part of revised roles — A European Space Agency astronaut will fly on the Artemis 3 moon mission, part of ongoing negotiations over Europe's broader role in the program. _Significance: Medium._ (SpaceNews)
• Hubble and Webb capture stunning composite of Black Eye Galaxy — A new image of Messier 64 combines data from both telescopes across ultraviolet, visible, and infrared wavelengths, revealing the galaxy's structure in unprecedented detail. _Significance: Medium._ (NASA News)
• Chandra may have found a supernova remnant in the galactic center — Using X-ray data, astronomers identified the expanding remains of an exploded star in a crowded region at the middle of our Milky Way. _Significance: Medium._ (NASA News)
• Hubble images a swarm of galaxies — The space telescope captured the galaxy cluster MACS0329-0211, a dense grouping of galaxies bound together by gravity. _Significance: Low._ (NASA News)
• SpaceX Dragon to depart ISS on June 16 — The cargo spacecraft will return scientific samples and hardware to Earth, with live coverage of its undocking. _Significance: Low._ (NASA News)

Life Sciences & Medicine

• First complex cells had genes from a mix of species — The earliest eukaryotic cells (cells with a nucleus) built their genomes through successive waves of gene transfers from different organisms, not from a single ancestor. _Significance: High._ (Ars Technica Science)
• Venus flytraps may snap shut through a different mechanism than thought — Detailed experiments suggest the trap closure isn't driven by water movement through cells, as widely believed, but by an alternative physical process. _Significance: Medium._ (New Scientist)
• Gen Z's "relationship recession" is worse than previously measured — New research shows that earlier studies missed a key factor, making the decline in steady relationships among young adults even steeper than reported. _Significance: Medium._ (New Scientist)
• Jennifer Doudna discusses the future of gene editing — In a new podcast episode, the Nobel Laureate reflects on CRISPR's discovery, its explosive growth, and the hurdles ahead for genome-editing technology. _Significance: Medium._ (Quanta Magazine)

Physics & Materials

• Time could be a quantum illusion, a toy universe suggests — An experiment using extremely cold atoms showed that time can emerge from quantum interactions rather than existing as a fundamental property of the universe. _Significance: High._ (New Scientist)
• Quantum computer mines cryptocurrency faster and more efficiently — A superconducting quantum computer joined a network mining an experimental cryptocurrency called Quip, outperforming conventional machines in both speed and energy use. _Significance: Medium._ (New Scientist)

Climate & Earth Science

• El Niño has officially begun, and it could be a "super" El Niño — Global weather agencies declared the start of the climate pattern, which typically boosts extreme weather worldwide and could lead to record temperatures. _Significance: High._ (New Scientist)
• Alaskans will lose critical ocean monitoring after NSF decommissions network — The National Science Foundation is shutting down an ocean monitoring network, putting Alaska's multibillion-dollar fishing industry and vulnerable coastal communities at risk. _Significance: High._ (Ars Technica Science)
• Politics may be encroaching on the National Academies of Science — A pending report on climate attribution (linking specific weather events to climate change) could set the stage for political conflict with the influential scientific advisory body. _Significance: Medium._ (Ars Technica Science)
• ESA awards contracts for next-gen radar imaging satellites — Thales Alenia Space and Airbus Defence and Space will build the next generation of radar satellites for Europe's Copernicus Earth observation program. _Significance: Medium._ (SpaceNews)

Technology-Driven Science

• Astronomers fear orbital data centers will interfere with observations — As SpaceX prepares to launch orbital data center spacecraft as soon as next year, astronomers warn these satellites could cause serious interference with telescopes. _Significance: High._ (SpaceNews)
• Aerospace executives say AI fills worker shortages, not replaces jobs — Industry leaders view artificial intelligence as a necessary tool for an overstretched industrial base rather than a threat to employment. _Significance: Medium._ (SpaceNews)
• NASA funds new gamma-ray detector tech for robotic missions — A prototype gamma-ray sensor will be tested on a robotic arm demonstration during NASA's upcoming Fly Foundational Robots mission. _Significance: Low._ (NASA News)

Upcoming: Launches & Publication Dates
