Chandra Space Telescope: Revealing the Invisible Universe

Posted by in categories: climatology, cosmology

The Chandra X-Ray Observatory is a NASA telescope that looks at black holes, quasars, supernovas, and the like – all sources of high energy in the universe. It shows a side of the cosmos that is invisible to the human eye.

After more than a decade in service, the observatory has helped scientists glimpse the universe in action. It has watched galaxies collide, observed a black hole with cosmic hurricane winds, and glimpsed a supernova turning itself inside out after an explosion.

The telescope – billed as one of NASA’s Great Observatories along with the Hubble Space Telescope, Spitzer Space Telescope and the Compton Gamma Ray Observatory – has been a public relations tool for the agency, as well. Its pictures are frequently used by NASA in press releases.

NASA is announcing a new discovery from Mars on Thursday — here’s how to watch it live

Posted by in categories: climatology, space

Here’s how to watch the announcement live.


NASA’s Curiosity Rover has found some new and exciting information about Mars, and the space agency is announcing that discovery to the world on Thursday.

The Curiosity Rover launched from Earth in November 2011 and landed on Martian soil on August 6, 2012. It has since been cruising around the red planet’s surface, functioning as a 9-foot-wide roving science machine.

Tesla has ‘about 11,000’ energy storage projects underway in Puerto Rico, says Elon Musk

Posted by in categories: climatology, Elon Musk, sustainability

Tesla is apparently significantly ramping up its effort to help rebuild the power grid in Puerto Rico after it was destroyed by hurricanes last year.

After having completed hundreds of energy storage project on the islands in the last few months, Tesla CEO Elon Musk now says that they have ‘about 11,000’ energy storage projects underway in Puerto Rico, which means something big is in the work.

Atomic-scale manufacturing now a reality

Posted by in categories: climatology, particle physics, robotics/AI

Scientists at the University of Alberta have applied a machine learning technique using artificial intelligence to perfect and automate atomic-scale manufacturing, something which has never been done before. The vastly greener, faster, smaller technology enabled by this development greatly reduces impact on the climate while still satisfying the insatiable demands of the information age.

“Most of us thought we’d never be able to automate atomic writing and editing, but stubborn persistence has paid off, and now Research Associate Moe Rashidi has done it,” said Robert Wolkow, professor of physics at the University of Alberta, who along with his Research Associate has just published a paper announcing their findings.

“Until now, we printed with about as efficiently as medieval monks produced books,” explained Wolkow. “For a long while, we have had the equivalent of a pen for writing with atoms, but we had to write manually. So we couldn’t mass produce atom-scale devices, and we couldn’t commercialize anything. Now that has all changed, much like the disruption following the arrival of the printing press for those medieval monks. Machine learning has automated the atom fabrication process, and an atom-scale manufacturing revolution is sure to follow.”

Beams of antimatter spotted blasting towards the ground in hurricanes

Posted by in categories: climatology, particle physics, space

Although Hurricane Patricia was one of the most powerful storms ever recorded, that didn’t stop the National Oceanic and Atmospheric Administration (NOAA) from flying a scientific aircraft right through it. Now, the researchers have reported their findings, including the detection of a beam of antimatter being blasted towards the ground, accompanied by flashes of x-rays and gamma rays.

Scientists discovered terrestrial gamma-ray flashes (TGFs) in 1994, when orbiting instruments designed to detect deep space gamma ray bursts noticed signals coming from Earth. These were later linked to storms, and after thousands of subsequent observations have come to be seen as normal parts of lightning strikes.

The mechanisms behind these emissions are still shrouded in mystery, but the basic story goes that, first, the strong electric fields in thunderstorms cause electrons to accelerate to almost the speed of light. As these high-energy electrons scatter off other atoms in the air, they accelerate other electrons, quickly creating an avalanche of what are known as “relativistic” electrons.

America’s water infrastructure is failing—but here’s how we could start to fix it

Posted by in categories: climatology, life extension, sustainability

America’s water is under threat from many sides. It faces pollution problems, outdated infrastructure, rising costs, and unprecedented droughts and rainfall patterns as the climate changes. Yet at a recent event hosted by the Columbia Water Center, the tone was cautiously optimistic, and the conversation centered on solutions.

“If we have aging that’s falling apart, and we’re dealing with climate variability and change, isn’t that a good opportunity to actually do something?” suggested Upmanu Lall, director of the Columbia Water Center.

For decades, the U.S. has been a leader in . Now we’re falling behind; in the latest infrastructure report card, dams, drinking water and wastewater all received D ratings. But Lall thinks the country could get an A. Here are some of the solutions, presented at the event, that could help to get us there.

Gigantic Waves That Control Earth’s Weather Have Once Again Been Detected Roaring Across The Sun

Posted by in categories: climatology, space

Astronomers have speculated for decades that the giant waves that meander through the Earth’s atmosphere and oceans, driving the weather, might also exist on the Sun. Now those waves have been unambiguously detected inside the Sun, and found to be very similar to those on Earth.

These Rossby waves, or planetary waves, naturally occur in rotating fluids. It is the rotation of the Earth that causes Rossby waves to propagate through the atmosphere and ocean, affecting the climate and weather.

The Sun rotates, too — so, theoretically at least, a similar phenomenon should be taking place in the gases and plasma that make up its layers. Indeed, it should be taking place in all rotating fluid systems.

Twin spacecraft to weigh in on Earth’s changing water

Posted by in categories: climatology, health

A pair of new spacecraft that will observe our planet’s ever-changing water cycle, ice sheets and crust is in final preparations for a California launch no earlier than Saturday, May 19. The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission, a partnership between NASA and the German Research Centre for Geosciences (GFZ), will take over where the first GRACE mission left off when it completed its 15-year mission in 2017.

GRACE-FO will continue monitoring monthly changes in the distribution of mass within and among Earth’s atmosphere, oceans, land and ice sheets, as well as within the solid Earth itself. These data will provide unique insights into Earth’s changing climate, Earth system processes and even the impacts of some human activities, and will have far-reaching benefits to society, such as improving water resource management.

“Water is critical to every aspect of life on Earth—for health, for agriculture, for maintaining our way of living,” said Michael Watkins, GRACE-FO science lead and director of NASA’s Jet Propulsion Laboratory in Pasadena, California. “You can’t manage it well until you can measure it. GRACE-FO provides a unique way to measure water in many of its phases, allowing us to manage water resources more effectively.”
