Early Mars might have been a warm version of modern Titan and at least as promising, if not more promising, as a location for the origin of life.

A new study reveals that Mars was born wet, with a dense atmosphere allowing warm-to-hot oceans for millions of years. This discovery was recently published in the journal Earth and Planetary Science Letters. To arrive at this conclusion, researchers created the first model of the evolution of the Martian atmosphere, which links the high temperatures associated with Mars’ molten formation to the creation of the first oceans and atmosphere.

Astronomers discover closest black hole to Earth

Black holes are the most extreme objects in the universe. Supermassive versions of these unimaginably dense objects likely reside at the centers of all large galaxies. Stellar-mass black holes—which weigh approximately five to 100 times the mass of the sun—are much more common, with an estimated 100 million in the Milky Way alone.

Only a handful have been confirmed to date, however, and nearly all of these are "active"—meaning they shine brightly in X-rays as they consume material from a nearby stellar companion, unlike dormant black holes which do not.

Swirling around the planet’s equator, the rings of Saturn are a dead giveaway that the planet is spinning at a tilt. The belted giant rotates at a 26.7-degree angle relative to the plane in which it orbits the sun.

A new study led by the University of Bonn and the University of Saint Andrews (Scotland) challenges this view of the Universe. The results suggest that the dwarf galaxies of Earth’s second closest galaxy cluster – known as the Fornax Cluster – are free of such dark matter halos. The study appeared in the journal Monthly Notices of the Royal Astronomical Society.

An asteroid wider than two football fields zoomed past Earth in the wee hours of Thursday (Aug. 4). The asteroid was set to pass at 12:23 a.m. (ET).

NASA astronomers discovered the asteroid, known as 2022 OE2, just days ago, on July 26. The meaty space rock is estimated to measure between 557 and 1,246 feet (170 to 380 meters) wide, which is about twice as wide as an American football field is long. Astronomers also confirmed that 2022 OE2 is an Apollo-class asteroid, which means it orbits the sun and crosses the path of Earth's orbit, Live Science previously reported.

Scientists have discovered dark matter around galaxies that existed about 12 billion years ago, the earliest detection yet of this mysterious substance that dominates the universe.

The findings, achieved by a collaboration led by researchers from Japan's Nagoya University, suggest that dark matter in the early universe is less 'clumpy' than predicted by many current cosmological models. If further work confirms this theory, it could change scientists' understanding of how galaxies evolve and suggest that the fundamental rules governing the cosmos could have been different when the 13.7 bil...    Learn More ››

How did Earth avoid a Mars-like fate? Ancient rocks hold clues

  1 year ago (Mon, Aug 01, 2022 at 11:09 AM)

Approximately 1,800 miles beneath our feet, swirling liquid iron in the Earth’s outer core generates our planet’s protective magnetic field. This magnetic field is invisible but is vital for life on Earth’s surface because it shields the planet from solar wind—streams of radiation from the sun.

About 565 million years ago, however, the magnetic field’s strength decreased to 10 percent of its strength today. Then, mysteriously, the field bounced back, regaining its strength just before the Cambrian explosion of multicellular life on Earth.

Russia has its eyes on a space station of its own.

The nation announced this week that it intends to pull out of the International Space Station (ISS) consortium after 2024. The timing of that move is uncertain, but Russia wants it to dovetail with the readiness of the planned Russian Orbital Service Station (ROSS).

We just got a better idea of what ROSS will look like and how it will operate (if the outpost does indeed end up being built), thanks to pictures and information released by Roscosmos, Russia's federal space agency. For example, the first phase of the outpost's assembly, targ...    Learn More ››

Why is gravity so weak? The answer may lie in the very nature of space-time

  1 year ago (Fri, Jul 29, 2022 at 09:12 AM)

Why is gravity so weak compared to the other four fundamental forces?

Even if it were a billion times stronger, it would still be the weakest force — by a factor of a billion billion. The strange feebleness of gravity sticks out, almost demanding an answer.

Strangely, the solution to gravity's weakness may not lie in gravity itself but in the mechanics of the Higgs boson and the very nature of space-time.

James Webb Space Telescope beats its own record with potential most distant galaxies

  1 year ago (Fri, Jul 29, 2022 at 08:58 AM)

Astronomers are now discovering record-breaking distant galaxies by the dozen while sifting through the treasure trove of data now being collected by the James Webb Space Telescope (JWST or Webb). Among them are several galaxies dating back to just over 200 million years after the Big Bang.

Prior to the launch of the James Webb Space Telescope, the most distant confirmed galaxy known was GN-z11, which astronomers saw as it was about 420 million years after the Big Bang, giving it what astronomers call a redshift of 11.6.

SpaceX is fighting against a possible regulatory change, saying it could cripple the company's Starlink satellite-internet business.

The potential change involves the 12 gigahertz (GHz) frequency band, which SpaceX's Starlink spacecraft and many other satellites use to beam data to the ground.

Early last year, the U.S. Federal Communications Commission (FCC) began thinking about opening the band up for extensive terrestrial use, as The Verge noted(opens in new tab). Dish Network has thrown its hat into this ring, proposing to use the 12 GHz band for its new 5G network.

Why Jupiter doesn’t have rings like Saturn

  1 year ago (Fri, Jul 22, 2022 at 01:09 PM)

Because it’s bigger, Jupiter ought to have larger, more spectacular rings than Saturn has. But new UC Riverside research shows Jupiter’s massive moons prevent that vision from lighting up the night sky.

“It’s long bothered me why Jupiter doesn’t have even more amazing rings that would put Saturn’s to shame,” said UCR astrophysicist Stephen Kane, who led the research.

“If Jupiter did have them, they’d appear even brighter to us, because the planet is so much closer than Saturn.” Kane also had questions about whether Jupiter once had fantastic rings and lost them. It i...    Learn More ››

Astronomers at MIT and universities across Canada and the United States have detected a strange and persistent radio signal from a far-off galaxy that appears to be flashing with surprising regularity.

The signal is classified as a fast radio burst, or FRB — an intensely strong burst of radio waves of unknown astrophysical origin, that typically lasts for a few milliseconds at most. However, this new signal persists for up to three seconds, about 1,000 times longer than the average FRB. Within this window, the team detected bursts of radio waves that repeat every 0.2 seconds in a clear pe...    Learn More ››

Space rocket junk could have deadly consequences unless governments act

The re-entry of abandoned stages of rockets left in orbit from space launches have a six to 10 per cent chance of severely injuring or killing a human being in the next decade, according to a new UBC study.

Researchers say governments need to take collective action and mandate that rocket stages are guided safely back to Earth after their use, which could increase the cost of a launch, but potentially save lives.

“Is it permissible to regard the loss of human life as just a cost of doing business, or is it something that we should seek to protect when we can? And that’s the crucial p...    Learn More ››

Earth's magnetic field: Explained

  1 year ago (Thu, Jul 07, 2022 at 10:26 AM)

Earth's magnetic field — also known as the geomagnetic field — is generated in our planet's interior and extends out into space, creating a region known as the magnetosphere.

Without the magnetic field, life on Earth as we know it would not be possible as it shields us all from the constant bombardment by charged particles emitted from the sun — the solar wind. (To learn what happens to a planet when it loses its magnetic field, you only need to look at Mars.)

Earth has two sets of poles, geographic pole and magnetic poles. Earth's magnetic field can be visualized if you imagine ...    Learn More ››
