NASA Develops Flexible Radar Antennas for Mars SkyFall Mission Helicopters

A tiny helicopter drone has a small white cape

Engineers at the Jet Propulsion Laboratory have developed 5-ounce flexible radar antennas that act like tiny capes, allowing the rotorcraft to map shallow subsurface ice during dozens of planned flights. Orbiting spacecraft have spent decades mapping Mars from above, but those high-altitude instruments cannot see the first few feet of material lying just beneath the … Read more

Dolphins Use Sea Shells as Tools to Hunt Fish off Queensland, Australia

Dolphins Use Sea Shells as Tools to Hunt Fish off Queensland, Australia

Marine biologists have documented Indo-Pacific bottlenose dolphins using large sea shells to hunt fish off Queensland, Australia, marking only the second known location worldwide for this rare behavior. Researchers recorded two shelling events in 2025 and captured footage suggesting the complex foraging skill is passed directly from mother to calf. Rare Foraging Behavior Documented in … Read more

JWST Astronomers Discover Ancient Black Hole Star MoM-BH-1

JWST Astronomers Discover Ancient Black Hole Star MoM-BH-1

Astronomers using Popular Science have discovered an ancient cosmic object that bridges the gap between black holes and stars. Appearing just 660 million years after the Big Bang, the newly identified entity has been named MoM-BH*-1. Researchers describe the phenomenon as a completely new type of astrophysical source in which a central black hole is … Read more

Partial Solar Eclipse and Perseid Meteor Shower Visible Across Canada

Sky watchers across various regions of Canada are preparing for a partial solar eclipse on Wednesday, accompanied by favorable conditions for viewing the Perseid meteor shower. While regions such as parts of Spain, Iceland, and Greenland experience a total solar eclipse where the moon completely covers the solar disc, observers in Canada will see a … Read more

NASA Sends Software Update to Voyager 2 to Extend Instrument Life

NASA Sends Software Update to Voyager 2 to Extend Instrument Life

NASA engineers beamed a fresh software update nearly 13.3 billion miles to the Voyager 2 space probe, implementing a power-saving strategy dubbed the Big Bang to keep its remaining instruments operational for at least an extra year as both spacecraft navigate deep interstellar space. Power Margins and the Plutonium Supply on Voyager 2 Nearly 49 … Read more

UC Davis Researchers Identify Gene That Could Speed Up Avocado Breeding

Researchers at the University of California, Davis, have identified the single gene responsible for the daily opening and closing rhythm of avocado flowers. Published in the Proceedings of the National Academy of Sciences, the discovery unlocks a genetic marker to sort A- and B-type seedlings, eliminating years of breeding guesswork. Solving a Century-Old Pollination Mystery … Read more

Andromeda Galaxy Star Formation Slows Over Past 500 Million Years

Astronomers analyzing Hubble Space Telescope data report that the Andromeda galaxy has steadily slowed its star formation over the past 500 million years, dropping to one-fifth of a solar mass annually. Researchers suspect the compact companion galaxy M32 may be influencing the decline, though the exact cause remains unconfirmed. Our galactic next-door neighbor is visibly … Read more

Life on Earth May Have Originated Twice From Common Code, Study Suggests

Life on Earth May Have Originated Twice From Common Code, Study Suggests

An international research team has uncovered details about the evolutionary split between bacteria and archaea, leading to a radical proposition regarding Earth’s history, according to research published in The Debrief on August 5, 2026. While scientists have historically thought that a single event sparked life on Earth roughly 4 billion years ago, the study suggests … Read more

Titan Distance From Earth Varies by Hundreds of Millions of Kilometers

Illustration of Saturn and its rings against a starfield

Titan’s shifting distance from Earth ranges from roughly 1.2 billion to 1.65 billion kilometers depending on planetary alignment, stretching a signal’s one-way trip from an hour to past ninety minutes. The mammoth moon features a dense nitrogen atmosphere, methane liquid cycles, and a suspected subsurface ocean. Spacecraft exploring Saturn’s largest moon must account for an … Read more
