Scientists warn a potentially ‘super’ El Niño is forming

Climate researchers say the tropical Pacific is rapidly warming and could develop into a major El Niño event later in 2026, with some forecasts pointing to exceptionally high sea-surface temperatures. NOAA estimates about an 80% chance of El Niño developing by July, though the final strength will depend on shifting trade winds and other atmospheric factors Source 5.

Rubin Observatory data reveals 11,000+ new asteroids

Using preliminary data from the Vera C. Rubin Observatory’s Simonyi Survey Telescope, scientists have identified more than 11,000 new asteroids in our solar system. The haul includes hundreds of distant objects beyond Neptune and 33 previously unknown near-Earth objects, highlighting the telescope’s power for planetary defense and solar-system mapping Source 2.

ISC launches global survey on emerging technologies in science systems

The International Science Council has opened a worldwide survey to study how emerging technologies are changing science systems, with special emphasis on the Global South. The survey covers satellite connectivity, VR/XR, data infrastructure, and robotics/AI, and is open until June 22, 2026 Source 4.

University of Washington research probes how much water Earth-like planets need

Researchers at the University of Washington report that an Earth-sized planet may need at least 20% to 50% of Earth’s ocean water to sustain a crucial natural cycle that keeps water on the surface. The finding has implications for planetary habitability and how scientists assess potentially life-supporting exoplanets Source 2.

Juno captures close-up images of Jupiter’s moon Thebe

NASA’s Juno spacecraft recently imaged Thebe, one of Jupiter’s tiny moons, during a close approach. The observations add to Juno’s expanding legacy of high-resolution Jovian science and help researchers better understand the irregular moons surrounding the giant planet Source 1.

NASA’s Psyche mission shares a striking view of Mars’ Huygens Crater

NASA released a new image from the Psyche mission showing Huygens Crater on Mars, offering a dramatic look at the Red Planet ahead of the spacecraft’s 2029 arrival at asteroid Psyche. Scientists think the asteroid may be the exposed metal-rich core of an ancient planetesimal Source 3.

7

Hubble spots a mysterious galaxy lacking spiral arms

NASA’s Hubble Space Telescope has captured a galaxy with no spiral arms, a rare morphology that may represent a transition phase in galaxy evolution. Astronomers are using such unusual systems to understand how galaxies form, change shape, and stop forming stars Source 3.

8

MAVEN detects a first-of-its-kind atmospheric effect on Mars

NASA’s MAVEN mission has reportedly detected the first Zwan-Wolf effect deep in Mars’ atmosphere, adding a new piece to the puzzle of Martian weather and atmospheric dynamics. The result could help scientists refine models of how Mars’ atmosphere behaves over time Source 3.

Potential dark-matter imprint detected in gravitational waves

Scientists say they may have found a possible dark-matter-related signature in gravitational-wave data, though they stress the result is preliminary. More observations and analysis are needed before any claim of a confirmed dark matter detection can be made Source 3.

10

Astronomers track asteroid 2026 JH2 during close Earth flyby

Asteroid 2026 JH2 was discovered only days before its close pass by Earth, illustrating how quickly near-Earth objects can appear in survey data. Astronomers continue to refine its orbit and size estimates as part of ongoing efforts to monitor potentially hazardous objects Source 3.
