Bedtime Astronomy

Bennu: A Time Capsule from the Early Solar System: Asteroid Bennu is made of material from different regions of the solar system and even from other stars. NASA’s OSIRIS-REx mission returned samples from Bennu in 2023, revealing ancient stardust, water-altered minerals, and organic molecules. These findings show Bennu preserves a rich record of early solar system history, including evidence of space weathering and chemical changes driven by water. Because the samples were collected directly in space, they offer an uncontaminated glimpse into the building blocks of planets and life.

In this week:
Rare Black Hole Feeding on a Star – Scientists observed a rare intermediate-mass black hole (HLX-1) tearing apart a star in a star cluster far from its galaxy’s center. This event, called a tidal disruption, allowed researchers to study how such black holes grow and possibly evolve into supermassive ones. It also supports theories about black hole formation and galaxy growth.Moon-Bound Telescope LuSEE-Night – A special radio telescope is being sent to the far side of the Moon to detect faint signals from the universe’s “Dark Ages,” a period before stars existed.

Dark Energy Might Be Changing Over Time
Scientists have combined data from over 2,000 exploding stars to better study dark energy—the mysterious force causing the universe to expand. New analysis suggests dark energy may not be constant, possibly challenging current theories. This could have major implications for how the universe evolves or ends. More data from future telescopes will help clarify the picture.

Scientists propose that "dark dwarfs"—brown dwarfs powered by dark matter—could reveal what dark matter is made of. Meanwhile, LIGO and its partners detected the most massive black hole merger ever seen, offering new insights into black hole formation. At the same time, new simulations suggest there may be many hidden, faint galaxies orbiting the Milky Way, helping to solve a mystery in our understanding of dark matter and galaxy formation.

NASA's new SPHEREx telescope is mapping the entire sky in infrared, helping scientists study the origins of stars, planets, and life—and the data is shared publicly. Researchers also propose a new type of glowing object called a "dark dwarf," powered by dark matter, which could offer clues about what dark matter is. Meanwhile, a giant object named 3I/ATLAS, recently spotted speeding through our solar system, is confirmed to be interstellar and may reveal how planets form in other star systems.

Scientists are developing new ways to explore hidden aspects of the universe. One approach uses powerful superconducting magnets to detect high-frequency gravitational waves—tiny ripples in space that current detectors often miss. Another proposes finding dark matter by spotting tiny primordial black holes through their Hawking radiation as they pass through our solar system, using existing instruments like the Alpha Magnetic Spectrometer. Meanwhile, astronomers are rethinking the search for the universe’s first stars, suggesting we look in slightly "polluted" galaxies where Population III stars may still shine alongside early supernova debris, making them easier to detect.

The Vera Rubin Observatory in Chile has released its first dazzling images, showcasing star-forming nebulae and galaxy clusters with unprecedented clarity. Designed to lead the Legacy Survey of Space and Time (LSST), the observatory will scan the night sky over ten years to explore billions of galaxies, track cosmic events, and detect unknown objects. Named after Vera Rubin, a pioneer in dark matter research, the observatory has already found over 2,000 new asteroids.

Meanwhile, scientists may be closing in on the elusive Planet Nine using infrared data from Japan’s AKARI telescope.

Separately, radio astronomers are using hy...

Simulating the Universe’s First Light with SKA-Low Scientists created an advanced simulation of what the SKA-Low radio telescope will detect when it starts observing the early universe. The project focuses on capturing ultra-faint 21-cm hydrogen signals from the Cosmic Dawn and the Epoch of Reionization—eras when the first stars and galaxies lit up the cosmos after a long dark age. This simulation includes realistic foreground interference, technical noise, and cosmic signals, helping researchers refine data analysis techniques before SKA-Low becomes operational. The goal is to study the universe’s first light...

This Week in Astronomy: New skepticism surrounds the potential biosignatures detected on exoplanet K2-18b, as revised analyses question the strength and interpretation of the chemical evidence. Meanwhile, theorists explore the idea that primordial black holes—stabilized by a “memory burden” effect—could be the true nature of dark matter, with future gravitational wave observatories poised to test this. Separately, new findings suggest that a massive ancient impact may have triggered the Moon’s now-lost magnetic field.
