Giant magnetofossils suggest ancient ocean life had built-in ‘GPS’ and may shed light on Mars particles

Some ancient marine organisms produced mysterious magnetic particles of unusually large size, which can now be found as fossils in marine sediments.

How a nutrient spark turned Earth into an oxygen world

A new study has revealed how phosphorus, a nutrient essential for photosynthesis, surged into ancient oceans and started Earth’s first major rise in atmospheric oxygen more than 2 billion years ago.

Constraints on solar power satellites are more ground-based than space-based, says study

Space-based solar power has been gaining more and more traction recently. The recent success of Caltech’s Space Solar Power Project, which demonstrated the feasibility of transmitting power from space to the ground, has been matched by a number of pilot projects throughout the world, all of which are hoping to tap into some of the […]

US soliciting new bids for Moon mission amid SpaceX delays: NASA chief

NASA is seeking bids for its planned Moon mission to compete against SpaceX, Elon Musk’s company that the US space agency’s chief said Monday is “behind.”

What do we do if SETI is successful?

The Search For Extra Terrestrial Intelligence (SETI) is evolving. We’ve moved on from the limited thinking of monitoring radio waves to checking for interstellar pushing lasers or even budding Dyson swarms around stars. To match our increased understanding of the ways we might find intelligence elsewhere in the galaxy, the International Academy of Astronautics (IAA) […]

Starship could cut the travel time to Uranus in half

The ice giants remain some of the most interesting places to explore in the solar system. Uranus in particular has drawn a lot of interest lately, especially after the 2022 Decadal Survey from the National Academies named it as the highest priority destination. But as of now, we still don’t have a fully fleshed out […]

Alien civilizations may only be detectable for a cosmic blink of an eye

Is anybody out there? Probably. Most stars have planets; we’ve discovered more than 6,000 exoplanets thus far, and the most basic statistics point toward the existence of countless potentially habitable worlds in the universe. But when we have looked for any scrap of evidence for alien civilizations, we have found nothing so far. The question […]

Distant galaxy A1689-zD1 found to have unusually low dust-to-gas ratio

Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/sub-millimeter Array (ALMA), an international team of astronomers has carried out comprehensive multiwavelength observations of a distant massive galaxy known as A1689-zD1.

What happened to those ‘little red dots’ Webb observed?

When the James Webb Space Telescope (JWST) began operations, one of its earliest surveys was of galaxies that existed during the very early universe. In December 2022, these observations revealed multiple objects that appeared as “little red dots” (LRDs), fueling speculation as to what they might be. While the current consensus is that these objects […]

How we sharpened the James Webb telescope’s vision from a million kilometers away

After Christmas dinner in 2021, our family was glued to the television, watching the nail-biting launch of NASA’s US$10 billion (AU$15 billion) James Webb Space Telescope. There had not been such a leap forward in telescope technology since Hubble was launched in 1990.

Follow-up observations by Webb confirm GRB 250702B is most energetic cosmic explosion ever recorded

Considering the immense size of the universe, it’s no surprise that space still holds plenty of secrets for us. Recently, astronomers believe they stumbled upon a kind of cosmic blast never seen before, and it’s challenging what we thought we knew about how stars die.

How to watch the Orionid meteor shower, debris of Halley’s comet

The Orionids—one of two major meteor showers caused by remnants from Halley’s comet—will peak with the arrival of a new moon, providing an excellent opportunity to see shooting stars without interference from moonlight.
