2018 was fourth hottest year on record: researchers

WASHINGTON, United States (AFP) – he last four years have been the world’s hottest since record-keeping began, with 2018 the fourth warmest on record, according to data published Thursday by US research group Berkeley Earth. Temperatures in 2018 were around 1.16 degrees Celsius (2.09 degrees Fahrenheit) above the average temperature of the second half of the 19th century, from 1850-1900, often used as a pre-industrial baseline for global temperature targets. “Global mean temperature in 2018 […]

How to drive a robot on Mars

by Ivan Couronne Agence France Presse GREENBELT, United States (AFP) — Some 78 million miles (126 million kilometers) from Earth, alone on the immense and frigid Red Planet, a robot the size of a small 4×4 wakes up just after sunrise. And just as it has every day for the past six years, it awaits its instructions. Around 9:30 Mars time, a message arrives from California, where it was sent 15 minutes earlier. “Drive forward […]

NASA counts down to launch of laser study of ice sheets

  by Kerry Sheridan Agence France Presse TAMPA, United States (AFP) — NASA counted down Saturday to the launch of its $1 billion ICESat-2 mission, using advanced lasers to uncover the true depth of the melting of Earth’s ice sheets. The mission will inform sea level rise forecasts and is “exceptionally important for science,” according to Richard Slonaker, ICESat-2 program executive at NASA. The half-ton satellite should reveal unprecedented detail about the current thickness of […]

Mars makes closest approach to Earth in 15 years

LOS ANGELES, United States (AFP) — Earth’s neighboring planet, Mars, is closer than it has been in the past 15 years, offering unusually bright views of the Red Planet’s auburn hues. “The Red Planet and Earth haven’t been this close since 2003, and won’t be again until 2035,” NASA said. Astronomers around the world trained their telescopes on the sky on July 31, when the Red Planet was 35.8 million miles (57.6 million kilometers) away. […]

Two sportscar-sized satellites in orbit to measure Earth’s water

by Ivan Couronne Agence France Presse WASHINGTON, United States (AFP) — A SpaceX rocket Tuesday blasted off a duo of sports car-sized satellites built by the US and Germany to reveal changes in sea level rise, ice melt and drought on Earth. “Three, two, one, liftoff!” said a SpaceX commentator as the Falcon 9 rocket launched from Vandenberg Air Force Base in California at 12:47 pm Pacific time (1947 GMT). The $521 million payloads, called […]

Seize this rare triple treat: the super blue blood moon tonight; next one to happen in Dec 2028

  The phrase once in a blue moon means a thing that happens rarely. And such an event will happen tonight, Wednesday, January 31. What will happen is not just a blue moon, but a “super blue blood moon” – when skygazers will catch a rare triple treat of a glimpse of the giant crimson moon, thanks to a rare lunar trifecta that combines a blue moon, a super moon and a total eclipse. The […]

Dimming the Sun to cool Earth could ravage wildlife: study

by Marlowe HOOD Agence France Presse PARIS, France (AFP) — Geoengineering schemes designed to deflect some of the Sun’s planet-warming rays would backfire if suddenly discontinued, wiping out species and entire ecosystems, a study published Monday warns. “Rapid warming after stopping geoengineering would be a huge threat to the natural environment and biodiversity,” said co-author Alan Robock, a professor at Rutgers University in New Jersey. Half-a-century’s worth of warming could rebound in a handful of […]

Worst-case global warming scenarios not credible: study

by Marlowe Hood Agence France Presse PARIS, France (AFP) — Earth’s surface will almost certainly not warm up four or five degrees Celsius by 2100, according to a study released Wednesday which, if correct, voids worst-case UN climate change predictions. A revised calculation of how greenhouse gases drive up the planet’s temperature reduces the range of possible end-of-century outcomes by more than half, researchers said in the report, published in the journal Nature. “Our study […]

‘To boldly grow’: Japan astronaut worried by space growth spurt

TOKYO, Japan (AFP) — A Japanese astronaut has sparked hilarity back on Earth after he claimed to have grown nine centimeters in space, making him worried he would not squeeze into the capsule home. Norishige Kanai, who is aboard the International Space Station, tweeted: “We had our bodies measured after reaching space, and wow, wow, wow, I had actually grown by as much as 9 centimeters (3.5 inches)!” “I have grown like a plant in […]

In desert of Oman, a gateway to life on Mars

by Alison Tahmizian Meuse Agence France-Presse DHOFAR, Oman (AFP) — In sunglasses and jumpsuits, a crew of European test astronauts is laying the groundwork for a Mars simulation in the barren expanse of the Omani desert, a terrestrial mission intended to pave the way to the red planet. The “analog astronauts” of the Austrian Space Forum — a volunteer-based collective — have arrived in Oman to begin preparations for a four-week simulation mission due to […]

One small doorstep for man: Cosmic mat welcomes aliens

by Glenda Kwek Agence France-Presse ADELAIDE, Australia (AFP) — It may look like an ordinary door mat, but its creators insist the conceptual art piece could encourage alien life to visit Earth — and help create a new kind of space archaeology. Dubbed the “Cosmic Welcome Mat” it features swirls of red, sky blue, and violet against a black border, and is meant to convey a warm reception to all sentient life in the universe. […]

Close call: house-sized passing asteroid to give Earth a near-miss Thursday, to test Earth’s warning systems

  by Mariëtte Le Roux Agence France Presse PARIS, France (AFP) — A house-size asteroid will give Earth a near-miss Thursday, passing harmlessly inside the Moon’s orbit while giving experts a rare chance to rehearse for a real-life strike threat. Dubbed 2012 TC4, the space rock will shave past at an altitude of less than 44,000 kilometres (27,300 miles) — just above the 36,000-km plane at which hundreds of geosynchronous satellites orbit the Earth. That […]
