Chile and Argentina among coldest places on Earth as polar anticyclone grips region

Chile and Argentina among coldest places on Earth as polar anticyclone grips region

On 30 June, both Chile and Argentina ranked among the coldest places on Earth, outside the polar regions. Governments in both countries issued early warnings and cold-weather alerts in response to the “polar-origin anticyclone” behind the extreme conditions, WMO said. The cold snap in South America contrasts blistering heat in the northern hemisphere, especially in […]

‘One Earth, One Health’: Yoga Day provides respite in a tumultuous world

‘One Earth, One Health’: Yoga Day provides respite in a tumultuous world

This powerful message of International Yoga Day, observed annually on 21 June, reverberated through UN Headquarters in New York on Friday as hundreds gathered to embrace the ancient, holistic practice. A familiar tradition now each year, the North Lawn once again transformed into an open-air yoga studio overlooking the East River.  Following a stretch of […]

NASA’s Perseverance Rover Gets the Dirt on Mars

NASA’s Perseverance Rover Gets the Dirt on Mars

The mission’s first two samples of regolith – broken rock and dust – could help scientists better understand the Red Planet and engineers prepare for future missions there. NASA’s Perseverance rover snagged two new samples from the Martian surface on Dec. 2 and 6. But unlike the 15 rock cores collected to date, these newest […]

Earth’s inner core may be oxygen-rich

Earth’s inner core may be oxygen-rich

Oxygen is the key substance for life and one of the most abundant elements in the Earth. However, it’s still unknown whether oxygen is present and in which form in the inner core with extreme high pressure and temperature conditions, and almost composed of pure iron. Scientists co-led by Dr. Jin Liu from HPSTAR (the […]

Edward Stone: 50 Years at NASA ends, but his brainchild Voyager’s Project goes on

Edward Stone: 50 Years at NASA ends, but his brainchild Voyager’s Project goes on

Stone’s remarkable tenure on NASA’s longest-operating mission spans decades of historic discoveries and firsts. Edward Stone has retired as the project scientist for NASA’s Voyager mission a half-century after taking on the role. Stone accepted scientific leadership of the historic mission in 1972, five years before the launch of its two spacecraft, Voyager 1 and Voyager 2. Under his guidance, […]

NASA’s Swift, Fermi missions detect exceptional cosmic blast

NASA’s Swift, Fermi missions detect exceptional cosmic blast

Astronomers around the world are captivated by an unusually bright and long-lasting pulse of high-energy radiation that swept over Earth Sunday, Oct. 9. The emission came from a gamma-ray burst (GRB) – the most powerful class of explosions in the universe – that ranks among the most luminous events known. On Sunday morning Eastern time, […]

No Picnic in the Clouds! It’s JPL aerobot

No Picnic in the Clouds! It’s JPL aerobot

JPL’s Venus Aerial Robotic Balloon Prototype Aces Test Flights A scaled-down version of the aerobot that could one day take to the Venusian skies successfully completed two Nevada test flights, marking a milestone for the project. The intense pressure, heat, and corrosive gases of Venus’ surface are enough to disable even the most robust spacecraft […]

Webb Telescope, Hubble Telescope Capture Detailed images of DART Impact

Webb Telescope, Hubble Telescope Capture Detailed images of DART Impact

Two of NASA’s Great Observatories, the James Webb Space Telescope and the Hubble Space Telescope, have captured views of a unique NASA experiment designed to intentionally smash a spacecraft into a small asteroid in the world’s first-ever in-space test for planetary defense. These observations of NASA’s Double Asteroid Redirection Test (DART) impact mark the first […]

NASA-Built ‘Weather Sensors’ Capture Vital Data on Hurricane Ian

NASA-Built ‘Weather Sensors’ Capture Vital Data on Hurricane Ian

A pair of microwave radiometers collected data on the storm as they passed over the Caribbean Sea aboard the International Space Station. Two recently launched instruments that were designed and built at NASA’s Jet Propulsion Laboratory in Southern California to provide forecasters data on weather over the open ocean captured images of Hurricane Ian on […]

NASA to live coverage Artemis I mission Demonstration Test, Host Media Call [Live schedule, streaming website details]

NASA to live coverage Artemis I mission Demonstration Test, Host Media Call [Live schedule, streaming website details]

NASA will provide live coverage with commentary of the upcoming Artemis I cryogenic demonstration test beginning at 7:15 a.m. EDT on Wednesday, Sept. 21. The demonstration test will allow teams to confirm the repair to a hydrogen leak seen during an early September Artemis I launch attempt, evaluate updated propellant loading procedures, and conduct additional evaluations. The demonstration will conclude […]

After 70 years, Jupiter moves closest to Earth on Sept 26

After 70 years, Jupiter moves closest to Earth on Sept 26

Jupiter is set to make its closest approach to Earth in the last 70 years and on September 26, stargazers can expect an excellent view when the giant planet reaches opposition. From the viewpoint of Earth’s surface, opposition happens when an astronomical object rises in the east as the Sun sets in the west, placing […]

Where do high-energy particles that endanger satellites, astronauts, airplanes come from?

Where do high-energy particles that endanger satellites, astronauts, airplanes come from?

For decades, scientists have been trying to solve a vexing problem about the weather in outer space: At unpredictable times, high-energy particles bombard the earth and objects outside the earth’s atmosphere with radiation that can endanger the lives of astronauts and destroy satellites’ electronic equipment. These flare-ups can even trigger showers of radiation strong enough […]
