SOLAR FLARE, TSUNAMI, AND RADIATION STORM: A strong flare on the sun this morning kicked off a remarkable sequence of events: a solar tsunami, a solar radio burst, a solar proton storm, a terrestrial radio blackout and a polar cap absorption event. The explosion also (almost certainly) hurled a CME toward Earth. Developing story @ Spaceweather.com.

GEOMAGNETIC STORM WATCH (G1-CLASS): Yesterday, the sun launched a coronal mass ejection (CME) toward Earth. Forecasters are divided on when it might arrive–sometime between midday on March 27th and early March 28th. The impact could spark minor G1-class geomagnetic storms with equinox auroras boosted by the “Russell-McPherron effect.” Full story @ Spaceweather.com.

James Webb: ‘Fully focused’ telescope beats expectations

The American space agency has achieved a major milestone in its preparation of the new James Webb Space Telescope.

Engineers say they have now managed to fully focus the $10bn observatory on a test star. The pin-sharp performance is even better than hoped, they add.

If we made contact with aliens, how would religions react?

The discovery of life on another planet might seem incompatible with faith in a deity. Yet many theologians are already open to the existence of extraterrestrials, argues the writer Brandon Ambrosino.

In 2014, NASA awarded $1.1M to the Center for Theological Inquiry, an ecumenical research institute in New Jersey, to study “the societal implications of astrobiology”.

Some were enraged. The Freedom From Religion Foundation, which promotes the division between Church and state, asked NASA to revoke the grant, and threatened to sue if NASA didn’t comply. While the FFR stated that their concern was the commingling of government and religious organisations, they also made it clear that they thought the grant was a waste of money. “Science should not concern itself with how its progress will impact faith-based beliefs.”

The FFR’s argument might well be undermined, however, when the day comes that humanity has to respond to the discovery of aliens. Such a discovery would raise a series of questions that would exceed the bounds of science. For example, when we ask, “What is life?” are we asking a scientific question or a theological one? Questions about life’s origins and its future are complicated, and must be explored holistically, across disciplines. And that includes the way we respond to the discovery of aliens.  READ MORE

(CNN)The Artemis I mission is another step closer to its lunar launch.

The massive 322-foot-tall (98 meters) stack, which includes NASA’s Space Launch System rocket topped by the Orion spacecraft, rolled out for its testing debut at Kennedy Space Center in Florida on Thursday.
The integrated stack, which sits on a mobile launcher, began its slow-moving crawl into launch position Thursday afternoon, with live coverage available on NASA’s website. The rollout officially began at 5:47 p.m. ET.
The rocket stack is seen inside the building before emerging on the crawler.

The 4-mile (6.4-kilometer) ride aboard one of the Apollo-era giant NASA crawlers from the assembly building to the launchpad could take up to 11 hours, according to NASA. The estimated arrival at the pad is around 4:30 a.m. ET on Friday.

CME SPARKS GEOMAGNETIC STORM: As predicted, a CME hit Earth’s magnetic field today, March 13th, sparking a moderately-strong G2-class geomagnetic storm. Depending on conditions in the CME’s wake, the storm could spill into March 14th. If it does, sky watchers in northern-tier US states might be able to see auroras after local nightfall. Stay tuned to Spaceweather.com for updates.

GEOMAGNETIC STORM WATCH (G2-CLASS): Earlier today the sun launched a full halo CME into space. The storm cloud is expected to hit Venus on March 13th followed by Earth later the same day. NOAA forecasters say that G2-class geomagnetic storms are possible when the CME arrives. Full story @ Spaceweather.com.

https://www.spaceweatheralerts.comNASA ROCKET PLUNGES INTO PULSATING AURORAS: Over the weekend, NASA launched a rocket from Alaska into an expanse of mysterious pulsating auroras. This type of aurora, which is a bit like a strobing checkerboard, is a favorite among tour guides because it is so unusual and mesmerizing. Researchers are just beginning to understand what makes it tick. Full story @ Spaceweather.com.

Mysterious new substance possibly discovered inside Earth’s core

The planet’s core could be a mushy mix of solid and liquid.

Earth’s inner core may be filled with a weird substance that is neither solid nor liquid, according to a new study.

For more than half a century, scientists believed that Earth‘s deepest recesses consist of a molten outer core surrounding a densely compressed ball of solid iron alloy. But new research, published Feb. 9 in the journal Nature, offers a rare insight into the inner structure of the planet — and it’s far weirder than previously thought.

New computer simulations suggest that Earth’s hot and highly pressurized inner core could exist in a “superionic state” — a whirling mix of hydrogen, oxygen and carbon molecules, continuously sloshing through a grid-like lattice of iron.

Third exoplanet found around closest star to Earth

Third exoplanet found around closest star to Earth

The planetary family around Proxima Centauri, the closest star to Earth, just keeps growing.

A little over four light-years away is Alpha Centauri, the closest star system to the Sun. And in August 2016, researchers announced they’d found a long-searched-for planet around Proxima Centauri, the smallest — and closest — component of this three-star system. Then, in January 2020, astronomers spotted a second world around Proxima Centauri. And now, the star’s family tree appears to be growing again: A third terrestrial planet has been found orbiting the nearest star to Earth.

A new addition

In a study published Feb. 10 in Astronomy & Astrophysics, astronomers announced the discovery of Proxima d. This tiny planet, weighing in at just one-quarter the mass of Earth, orbits Proxima Centauri every five days at a distance of some 2.5 million miles (4 million kilometers), or less than one-tenth the distance of Mercury from our own Sun. But because Proxima Centauri is a red dwarf with only about 12 percent the Sun’s mass and 14 percent its diameter, this puts Proxima d in the star’s habitable zone, where conditions are just right for liquid water to potentially exist on its surface.

Imagine a world where the clouds are made of metal and liquid rubies and sapphires rain down from the sky. A new study shows that, on the hot Jupiter exoplanet WASP-121 b, this could be the reality.

In 2015, scientists discovered WASP-121 b, a gas giant exoplanet 880 light-years from Earth. The alien world is what is known as a “hot Jupiter,” a class of gas giants that have physical similarities to Jupiter but orbit their stars much closer (hence, their “hot” nature). Since its discovery, researchers have further explored this world and its strange atmosphere.

In a new study, scientists using the Hubble Space Telescope have made the first detailed measurement of the atmosphere on the planet’s cooler nightside. And this nighttime atmosphere seems to have a number of strange and remarkable qualities including metal clouds and rain made of what could be liquid gems.

HUGE EXPLOSION ON THE FARSIDE OF THE SUN

2 Comments

HUGE EXPLOSION ON THE FARSIDE OF THE SUN: Earth might have just dodged a bullet. Earlier today, NASA’s STEREO-A spacecraft observed a tremendous coronal mass ejection (CME) emerging from the farside of the sun. Helioseismic maps of the sun’s farside suggest that a huge sunspot group may be responsible, and it will soon turn to face Earth. See the data and more @ Spaceweather.com.
