Big Bang Conditions Created in Lab.

By smashing gold particles together at super-fast speeds, physicists have basically melted protons, creating a kind of "quark soup" of matter that is about 250,000 times hotter than the center of the sun and similar to conditions just after the birth of the universe.

Astronomers spot nearest star-destroying black hole

Astronomers have detected a supermassive black hole ripping a passing star to shreds. Not only was this cataclysm closer to Earth than ever seen before, but its location and light emissions were unusual, hinting at a large unseen population of these events.

SETI uses VLA giant radio antennae to seek ETs

The search for extraterrestrial civilizations has gotten a major boost as SETI joins forces with the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) near Socorro, New Mexico.

It combines the giant radio telescope with a new processing system to increase the search's effectiveness by a factor of 1,000.

Russia's decision to remain on ISS til 2028 saves it from early demise

NASA has announced that Russia will remain a participant aboard the International Space Station (ISS) until 2028, ensuring the station's safe operation until it is finally vacated by all 15 international partners in 2030 before its deorbiting.
NASA has been exploring contingency plans in case Russia had backed out. Now we'll never know if they would have worked.

Vintage Apollo data shows Moon has a solid inner core

Looking back at data from the geology experiments left on the lunar surface by the Apollo missions half a century ago, scientists have finally determined that the Moon has a solid core surrounded by a fluid outer core similar to the Earth's.

Thirsty astronauts could just throw some Moon dust in the microwave

While there is water on the Moon, it’s not kept in convenient reservoirs, it’s locked away in the lunar soil. Now, a team of scientists has found that thirsty astronauts could one day refresh themselves fairly easily – by throwing a cup of Moon dirt in the microwave.

Over the past decade or so, increasing evidence has been found for water on the Moon, bound between the grains of the surface lunar dust, known as regolith. Its estimated abundance varies across the surface, with the highest concentrations at the poles where frozen deposits form in areas that never see direct sunlight.

Boom! Astronomers just watched the largest explosion in space rage for 3 years

Astronomers have witnessed the largest explosion in space.

The explosive event labeled AT2021lwx was observed to be ten times brighter than any known supernova, the explosions that occur as massive stars die. And whereas supernova explosions only last a few months, this explosive event has been raging for at least three years.

Mysterious dark energy is spread evenly across the cosmos

The anti-gravity force that is driving the accelerating expansion of the universe appears to be distributed uniformly across space and time.

Will we ever...hibernate in space?

Taking astronauts to Mars or further will take years. Should they be put into hibernation on the way? There are some surprising health benefits….

Saturn reclaims 'moon king' title with 62 newfound satellites, bringing total to 145

Sorry, Jupiter.
Astronomers have discovered 62 new moons orbiting the ringed planet Saturn.

The satellite haul brings the planet's total number of moons to over 100 and also means the gas giant takes back the crown as the solar system's "moon king" from Jupiter.

No lie....I have always thought of Saturn as Whitaker and Jupiter as Trammell. They just gobble up everything.

I should probably find new hobbies.

Webb confirms water in weird comet, but something else is missing

Asteroids and comets may seem very different – asteroids are dusty, dry balls of rock that orbit in a belt between Mars and Jupiter, while comets are icy, tailed and hail from beyond Neptune. But the line between them is getting fuzzier all the time, as some objects in the main asteroid belt have been seen to occasionally grow tails and haloes like comets. These are called active asteroids, or main-belt comets, which really only serves to confuse the issue further.

Jupiter probe Juno has close encounter with fiery Io

In a close encounter of the Jovian kind, NASA's Juno deep space probe has made its closest flyby yet of Jupiter's volatile moon Io. During its 51st orbit of the giant planet, the solar-powered robotic spacecraft came within 22,600 miles (35,500 km) of Io's volcanic surface.
First launched from what is now Cape Canaveral Space Force Station in Florida atop an Atlas V rocket on August 5, 2011 on the start of a seven-year mission, Juno is now well into its 12th year. On July 5, 2016, it went into orbit around Jupiter and has, to date, traveled over 510 million miles (820 million km).

New trio of telescopes scans the southern sky for gravitational waves

The new BlackGEM telescopic array at the European Southern Observatory’s (ESO’s) La Silla Observatory in Chile has officially begun scanning the southern skies, searching for the sources of gravitational waves.

NASA picks Blue Origin to make a second human-crewed lunar lander

NASA has picked Jeff Bezos’ Blue Origin to make a lunar lander for an upcoming Artemis mission to the Moon, the agency announced on Friday. As part of the $3.4 billion contract, there will be one uncrewed “demonstration mission” ahead of a human-crewed demo that’s set to take place in 2029 for the Artemis V mission, according to a press release.

SpaceX launches 10th crewed mission, third fully commercial flight

SpaceX on Sunday evening launched a commercial mission to the International Space Station carrying four people, including former NASA astronaut Peggy Whitson.

High-speed orbital data link drags space communications out of the '60s

Finally, a promising upgrade to the antique space radio systems that make orbital data transfer so ridiculously slow. Terran Orbit has set a new record for transmitting at high-speed from space to Earth as NASA's Pathfinder Technology Demonstrator 3 (PTD-3) CubeSat used an optical laser system to beam data from 300 miles (480 km) up to a ground station at a rate of 200 gigabits per second.

ESA to test a reusable origami heat guard for spacecraft

ESA is preparing to test a very cool new fold-out heat shield for protecting spacecraft on re-entry. The Pridwen won't burn away like ablative heat shields, and it'll also slow falling satellites down enough to be caught in a hover net.
