How Japan's space agency pulled off a daring expedition to snatch pieces of ancient space rock

How Japan's space agency pulled off a daring expedition to snatch pieces of ancient space rock

Here is how Japan's space agency pulled off a daring expedition to snatch pieces of the ancient space rock Ryugu.In a gray camouflage tee and blue denim jeans, Masaki Fujimoto is dressed all too casually for a man about to make history. Queen's Don't Stop Me Now has been playing on repeat, in his head, for weeks. One line is particularly prophetic for the 56-year-old astrophysicist. "I'm burning through the sky…"In less than 48 hours, a 16-inch-wide steel capsule will do just that, rocketing through the atmosphere before unfurling a parachute and gently landing in a sparsely populated area...

Ghost particle that crashed into Antarctica traced back to star shredded by black hole

Ghost particle that crashed into Antarctica traced back to star shredded by black hole

A black hole gobbled up a star in deep space and flung a high-energy subatomic bullet at the Earth. Don't worry, the planet's doing fine.On Oct. 1, 2019, Earth was struck by an invisible, high-energy cosmic bullet moving at almost the speed of light. Trillions of these intergalactic bullets pass through our bodies every second without us even knowing, so there's no great concern for the planet -- but this particular projectile was special. At the bottom of the world, the ghostly particle met its end after colliding with an ice molecule. Fortunately, it did so right next to an extremely...

NASA's Perseverance, China's Tianwen-1 and UAE's Hope reach Mars this month

NASA's Perseverance, China's Tianwen-1 and UAE's Hope reach Mars this month

Three missions to Mars have spent the last seven months hurtling through space. In February, they arrive.July 2020 was a huge month for Mars. Taking advantage of its nearby position in orbit, on a seven-month journey to the red planet. Now those spacecraft -- , the and the -- are arriving at their destination. They're poised to uncover the secrets our celestial neighbor hides within its atmosphere and barren plains and may even reveal . Although all three spacecraft will make it to orbit around Mars this month, NASA's Perseverance (or "Percy") gets to take center stage. It will be the only...

Star collision helps solve 16-year-old mystery of the Blue Ring Nebula

Star collision helps solve 16-year-old mystery of the Blue Ring Nebula

CNET también está disponible en español.Don't show this againA collision between two stars thousands of years ago produced two interstellar ice cream cones full of hot gas.Take a moment from this hellish year to imagine that a small star has been orbiting our sun. After eons, the . The chaotic smash leaves behind a star and a mesmerizing blue cloud of dust and gas, , spills out into the cosmos. The cloud extends to a distance of about 13 light-years, enough to engulf 10 solar systems stacked end to end. While such a fate doesn't await our sun (though it is 2020, so...), that exact scenario...

We've been filling space with dangerous debris for decades, and we may have gravely underestimated the problem

We've been filling space with dangerous debris for decades, and we may have gravely underestimated the problem

We're building a Great Garbage Shell around the Earth, full of defunct satellites and tiny pieces of junk.The Pacific Ocean is home to two monstrous, swirling vortices of human junk. Tangled fishing nets, garbage bags and millions of tiny pieces of plastic twirl in the waves east of Japan and sway in the current along the California coast. The kipple at opposite ends of the Pacific is connected by a stream of debris, weaving its way across the world's largest ocean.The disjointed mass of waste is known as the Great Pacific Garbage Patch. It's often portrayed as a , an artificial landmass...

A NASA telescope has uncovered definitive evidence of water on the moon. That's good news for future human and robotic exploration

A NASA telescope has uncovered definitive evidence of water on the moon. That's good news for future human and robotic exploration

A telescope in the back of a 747 finally puts to rest a longstanding question about lunar water.Eleven years ago, a trio of spacecraft changed forever. Data collected by the robotic travelers indicated Earth's only natural satellite was not a dry, dusty desert as we'd long believed. The spacecraft picked up the telltale chemical signature of water. Our moon wasn't soaking, but it was damp.Scientists couldn't pull apart the chemical signature to definitively say how much was "molecular" water, the stuff we know as H2O, and how much was hydroxyl, a molecule that's one hydrogen atom short of...

How the coronavirus origin story is being rewritten by a guerrilla Twitter group

The group, known as Drastic, has investigated, corrected, uncovered and agitated in a quest to uncover the pandemic's starting point.The Seeker poured a strong cup of chai and lit a cigarette. He was onto something. Alternating between a smartphone and a laptop, the former science teacher from the northeast Indian city of Bhubaneswar punched keywords into the search bar of CNKI, one of China's foremost databases of scientific papers.  Coronavirus, SARS, horseshoe bat, Yunnan. It was May 18, 2020. At the time, the novel coronavirus, SARS-CoV-2, had infected fewer than 5 million people...
