NASA Is Watching a Huge Anomaly Growing in Earth’s Magnetic Field
For years, NASA has monitored a strange anomaly in Earth’s magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest Africa.
This vast, developing phenomenon, called the South Atlantic Anomaly, has intrigued and concerned scientists for years, and perhaps none more so than NASA researchers.
The space agency’s satellites and spacecraft are particularly vulnerable to the weakened magnetic field strength within the anomaly, and the resulting exposure to charged particles from the Sun.
Astronomers capture giant planet forming 440 light-years from Earth
Astronomers may have caught a still-forming planet in action, carving out an intricate pattern in the gas and dust that surrounds its young host star. Using ESO’s Very Large Telescope (VLT), they observed a planetary disc with prominent spiral arms, finding clear signs of a planet nestled in its inner regions. This is the first time astronomers have detected a planet candidate embedded inside a disc spiral.
“We will never witness the formation of Earth, but here, around a young star 440 light-years away, we may be watching a planet come into existence in real time,” says Francesco Maio, a doctoral researcher at the University of Florence, Italy, and lead author of this study, published on July 21 in Astronomy & Astrophysics.
Astronomers share best-ever evidence that Betelgeuse has a secret companion star — and they’ve nicknamed it ‘her bracelet’
The red supergiant Betelgeuse likely has a companion star, astronomers have confirmed.
Long theorized to share an orbit with Betelgeuse — an extremely bright star that may go supernova in the next few thousand years — a sun-size companion star has finally appeared in unique observations taken with the Gemini North telescope high on Hawaii’s Mauna Kea.
