Researchers from The Australian National University have challenged the concept that Earth formed from the same material as the Sun — and thus has a “chondritic” composition — an idea that has been assumed accurate by planetary scientists for quite some

NASA is still not sure whether the rockets will be launched today but have continued rocket preparation of launch attempt in hope weather might be a “go”.The countdown for the mission was set and started at 7 p.m. EDT, Tuesday, March 20. (23:00 UTC, March 20,
Since the high probability of unacceptable weather is preventing a launch attempt on March 19 again, NASA has rescheduled the launch of its five suborbital sounding rockets from the Wallops Facility in Virginia as part of a study of the upper level jet stream to no
An equinox occurs twice a year, when the tilt of the Earth’s axis is inclined neither away from nor towards the Sun, the center of the Sun being in the same plane as the Earth’s equator. The term equinox can also be used in a broader sense, meaning the date when such a
Sunspot 1434 located in the southern hemisphere, produced a rapid M1.3 Solar Flare at 20:39 UTC on March 17, 2012. A Type II Sweep Frequency Event with a velocity of 1140 km/s was detected as well. Analysis of the M1.3 flare is ongoing to determine if it was
