These Scientists Mapped Every Large Solar Plant on The Planet, With Brilliant Results

An astonishing 82 percent decrease in the cost of solar photovoltaic (PV) energy since 2010 has given the world a fighting chance to build a zero-emissions energy system which might be less costly than the fossil-fueled system it replaces.   The International Energy Agency projects that PV solar generating capacity must grow ten-fold by 2040… Continue reading These Scientists Mapped Every Large Solar Plant on The Planet, With Brilliant Results

Astronomers May Have Discovered the First Extragalactic Planet

Astronomers have found evidence for a possible planet candidate in the M51 (“Whirlpool”) galaxy, representing what could be the first planet detected outside of the Milky Way. Chandra detected the temporary dimming of X-rays from a system where a massive star is in orbit around a neutron star or black hole (shown in the artist’s… Continue reading Astronomers May Have Discovered the First Extragalactic Planet

Why was the forecasted aurora a bust? :: WRAL.com

By Tony Rice, NASA Ambassador While observers in Iceland along with parts of Northern Europe and Russia enjoyed the northern lights, Thursday’s X-class solar flare and Coronal Mass Ejection (CME) of charged particles hurled into space, failed to put on the show further south. Why was this forecasted G3 geomagnetic storm a bust? Not unlike… Continue reading Why was the forecasted aurora a bust? :: WRAL.com

NASA Shares First Evidence of Planet Outside Our Galaxy

Astronomers say they have found evidence for the first time of a planet orbiting a star outside our Milky Way galaxy. The evidence was observed by a telescope operated by the American space agency NASA. It is called the Chandra X-ray Observatory. NASA says the orbiting observatory is the world’s most powerful X-ray telescope. NASA… Continue reading NASA Shares First Evidence of Planet Outside Our Galaxy

2021 Antarctic Ozone Hole 13th-Largest – Will Persist Into November or Even December

The 2021 Antarctic ozone hole reached its maximum area on October 7 and ranks 13th-largest since 1979, scientists from NASA and NOAA reported on October 27, 2021. This year’s ozone hole developed similarly to last year’s: A colder than usual Southern Hemisphere winter led to a deep and larger-than-average ozone hole that will likely persist… Continue reading 2021 Antarctic Ozone Hole 13th-Largest – Will Persist Into November or Even December

New Chinese launch firm signs deal for reusable rocket engines

HELSINKI — Rocket Pi of China has signed a deal with a liquid rocket engine maker for supply of engines to power its Darwin-1 reusable launch vehicle. The deal, announced by methane-liquid oxygen engine maker Jiuzhou Yunjian Oct. 30, is for Lingyun-70, 70-ton (sea level) thrust engines with deep throttling capabilities and 12.5-ton (vacuum) thrust… Continue reading New Chinese launch firm signs deal for reusable rocket engines

Astronomers may have spotted a planet in another galaxy for the first time

The hunt for exoplanets is venturing beyond the Milky Way. Astronomers using NASA’s Chandra X-ray Observatory have detected what might be the first signs of a planet in another galaxy. The team noticed dips in X-ray brightness that hint at a planet transiting in front of a star in the Messier 51 (aka M51) galaxy… Continue reading Astronomers may have spotted a planet in another galaxy for the first time
