35 years and 11 billion miles later, Voyager 1 still reporting from edge of interstellar space

35 years and 11 billion miles later, Voyager 1 still reporting from edge of interstellar space

NASA’s Voyager 1 spacecraft has entered a new region at the far reaches of our solar system that scientists feel is the final area the spacecraft has to cross before reaching interstellar space. Scientists refer to this new region as a magnetic highway for charged particles because our sun’s magnetic field lines are connected to […]

Scientists discover evidence of water ice at Mercury’s poles

Scientists discover evidence of water ice at Mercury’s poles

Mercury, the smallest and innermost planet in our solar system, revolves around the sun in a mere 88 days, making a tight orbit that keeps the planet incredibly toasty. Surface temperatures on Mercury can reach a blistering 800 degrees Fahrenheit — hot enough to liquify lead. Now researchers from NASA, MIT, the University of California […]

Wind speed increases to 300 mph in Jupiter’s Great Spot as its radius decreases

Wind speed increases to 300 mph in Jupiter’s Great Spot as its radius decreases

Jupiter’s Great Red Spot is as constant as the North Star. In other words, it only looks constant — its constancy depends on how long we watch it. … Last week John Rogers (British Astronomical Association) confirmed that the storm is still tightening its waistline. Rogers clocked the maelstrom’s rotation period by using images taken […]

8 years after entering Saturn’s orbit, Cassini captures season changes

PASADENA, Calif. — Posing for portraits for NASA’s Cassini spacecraft, Saturn and its largest moon, Titan, show spectacular colors in a quartet of images being released today. One image captures the changing hues of Saturn’s northern and southern hemispheres as they pass from one season to the next. A wide-angle view in today’s package captures […]

Curiosity eyes Mt. Sharp from a crater on Mars, and prepares to go there

The light peak is Mt. Sharp — an eventual destination of the Curiosity rover. … Curiosity’s is already on the move crossing the intermediate gravel field toward an interesting terrain feature named Glenelg. Curiosity has also already started analyzing its surroundings by zapping a nearby rock with its laser to analyze the chemical composition of […]
