Amelia Earhart, born July 1897, was an American aviatrix who became the first female pilot to fly solo over the Atlantic ocean, and received several awards for her achievements. Unfortunately, she disappeared while flying solo over the Pacific ocean in 1937. She was never found. I thought it would be a good thing to post about her, as even though she’s well known, it wouldn’t hurt to let more people know about her accomplishments. So to all of you budding aviatrices out there, don’t be put off. Make Ms. Earhart proud!

A view of a 20,000-year old supernova remnant of this giant cloud that resembles a Florida Manatee.

W50 is one of the largest supernova remnants ever viewed by the VLA. At nearly 700 light years across, it covers two degrees on the sky – that’s the span of four full Moons.

The enormous W50 cloud formed when a giant star, 18,000 light years away in the constellation of Aquila, exploded as a supernova around twenty thousand years ago, sending its outer gases flying outward in an expanding bubble.

The remaining, gravitationally-crushed relic of that giant star, most likely a black hole, feeds on gas from a very close, companion star. The cannibalized gas collects in a disk around the black hole. This system of a black hole and its feeder star shines brightly in both radio waves and X-rays and is known collectively as the SS433 microquasar.

300 million years ago a galaxy was murdered.

"Space is a dangerous place for galaxies. Collisions with other galaxies, near misses and other forms of violence can dramatically alter or even destroy them.

Our own Milky Way has gobbled up smaller galaxies in the past and is expected to be transformed from an elegant spiral into a diffuse blob of stars in a likely merger with the nearby Andromeda galaxy a few billion years from now.

Even when disturbances do not destroy galaxies, they can strip them of the gas they need to produce new generations of stars and planets, effectively sterilising them. The latest known victim of such intergalactic violence is called FGC 1287. It appears perfectly healthy in visible light, which shows only its stars, but new radio evidence from the Very Large Array in New Mexico reveal that it is severely wounded, bleeding a vast trail of gas into space.”

Your stomach is one of the most hostile environments on earth.
—  Human Physiology, an integrated approach, 5th Edit, D. Unglaub Silverthorn | It continues: “Bathed in acid strong enough to digest iron nails [ — from which] its walls [are] protected by a sticky mucus [—] and constantly churning, the stomach was once thought to be uninhabitable by any life form. However, scientists have discovered a remarkable organism that actually thrives in the stomach’s formidable environment.” | FYI, it’s Helicobacter pylori, associated with peptic ulcers.
