NASA unveils two new spacesuit prototypes for Moon to Mars exploration

October 16, 2019

The Orion Crew Survival System , a bright orange pressure suit, is the second suit that NASA launched. The Apollo moon suit, known as the Extravehicular Mobility Unit, or EMU, was famously so restricted that some astronauts preferred to "bunny hop", taking advantage of the moon's low gravity to lope over the surface.

NASA Confirms First All-Female Spacewalk

October 16, 2019

In a change to their brief, the pair will replace a faulty battery charge-discharge unit, which is now preventing a new lithium-ion battery installed earlier this month from powering the ISS. "It (doing without the BCDU) is manageable, but not something we'd want to live with in the long run", Todd told reporters. NASA originally planned an all-female spacewalk last spring, but had to cancel it because of a shortage of readily available medium-size suits.

Renewables overtake hydrocarbons in UK electricity generation

October 15, 2019

Fossil fuels made up four-fifths of the country's electricity fewer than 10 years ago, split between gas and coal, but the latest analysis by Carbon Brief shows that coal-fired power was less than 1% of all electricity generated. He said: "Already, we've cut emissions by 40% while growing the economy by two thirds since 1990". Another huge offshore wind farm was completed earlier this year.

NASA ICON Spacecraft Launches A Mission For Exploring The Space

October 15, 2019

Five seconds after the satellite's release, the attached Pegasus rocket ignited, sending Icon on its way. The spacecraft's solar panels efficiently deployed, indicating it has energy with all methods working. Full-fledged auroras appear near the poles in the ionosphere, but airglow is a fainter version of the same process that can happen nearly anyplace. But it's still bright enough for ICON's instruments to build up a picture of the ionosphere's density, composition and structure.

Discovery of 20 new moons puts Saturn ahead of Jupiter

October 12, 2019

Saturn and Jupiter , with 161 between them, account for almost 80% of these. One of the newly discovered retrograde moons is the farthest known moon around Saturn. It probably took the scientific community so long to discover the twenty-odd moons circling Saturn is because of the great distance of the planet from the Earth.

NASA found a weirdly salty 'ancient oasis' on Mars

October 09, 2019

This is evidence that a salty lake was evaporating from the surface around that time, scientists reported Monday in a new paper in Nature Geoscience . Pure salt is usually left behind when a lake dries and disappears, but these are mineral salts mixed in with sediment. Scientists liken the region's ancient environment to the South America's Altiplano , where alpine lakes and streams from the surrounding mountains feed a series of saline lakes on an arid, high-altitude plateau.

What If Planet 9 Is Actually a Tiny Black Hole?

October 02, 2019

That may be true, but black holes aren't all the same, and researchers believe so-called primordial black holes (PBHs) that were created shortly after the Big Bang may still exist. One of the prime hypotheses for Planet 9 is that it was a rogue planet captured by the sun. If Planet 9 is indeed a black hole , how does that change the search? However, the team now propose examining cosmic rays and gamma rays which could be emanating from the small black hole .

"The calving will not directly affect sea level , because the ice shelf was already floating, much like an ice cube in a glass of water", Dr Galton-Fenzi said.

China’s lunar probe may land on the moon’s far side tonight

October 01, 2019

The Moon is locked such that its orbit around the Earth is synchronised with its rotational speed-meaning that the far side is always pointing away from the planet. One of the mission's objectives is to study any exposed material from the mantle present at the landing site. For now, it plans to send a Chang'e 5 probe to the moon next year and have it return to Earth with samples - also not done since the Soviet mission in 1976.

'Planet Nine' may actually be a black hole

September 30, 2019

If they exist, such black holes could make up the 80% of the universe that scientists can't see. Dark matter is believed to account for 85 percent of all matter in the known universe. On average, the mysterious body orbits the sun at a distance 20 times farther than Neptune - about 18.6 billion miles. If Planet Nine did turn out to be a black hole, it would also explain why it has been so far impossible to spot as researchers have so far been looking for an object in visible light.

Planet Nine may be a primordial black hole

September 30, 2019

That's a scenario a pair of scientists describe in a new paper . They suggest that the orbit of the Sun has caught a free-floating " primordial black hole ".

The authors said that if they find these signals, it would mean that Planet Nine is actually a black hole.

Astronomers Discover Jupiter-like Planet Orbiting A Tiny Star

September 29, 2019

The red dwarf system is nearly 31 light years away and might contain another giant exoplanet. M-type red dwarfs are among the smallest and coolest stars, but by far the most common type of star in the Milky Way. This went on until these cores had built up to around ten Earth masses. "These clumps can grow until they collapse, forming a planet". Under the leading model for planetary formation, called the "core accretion" model, an object initially forms from solid particles in the disk and ...

The last supermoon of 2019

September 28, 2019

A supermoon is a full or almost full moon that coincides with lunar perigee, the point in the moon's elliptical orbit when it's nearest the Earth . On March 19, the moon is expected to reach perigee, which means it's at its closet point to our planet in its orbit. Grand Junction is not an ideal place for super moon viewing - at least not from my perspective.
