Most striking is the extreme speed with which it enters the atmosphere, the Earth is clearly growing larger with each second even from many km up!

B-21 bomber revealed

The B-21 bomber, formerly the Long Range Strike Bomber (LRS-B) is a proposed long-range strategic bomber for the United States Air Force, intended to be a heavy-payload stealth aircraft capable of carrying thermonuclear weapons. Initial capability is expected in the mid-2020s. A request for proposal to develop the aircraft was issued in July 2014. The Air Force plans to purchase 80–100 LRS-B aircraft at a cost of $550 million each (2010 dollars). A development contract was awarded to Northrop Grumman in October 2015.

Motes of dust in a sunbeam

“Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.” ― Carl Sagan, Pale Blue Dot : A Vision of the Human Future in Space

Muslim views on suicide bombing

At times like these, apologists are quick to remind us that most Muslims don't support terrorism and suicide bombings against civilians. This is true. Only about a third of them do, 500 million or so.

. Muslim Views on Suicide Bombing

All religions are equally wrong, but not all religions are equally dangerous. 50 years or more ago, it would have been Catholicism that was the most harmful. Today it is Islam.

Pluto enhanced/false color

New Horizons scientists made this false color image of Pluto using a technique called principal component analysis to highlight the many subtle color differences between Pluto's distinct regions. The image data were collected by the spacecraft’s Ralph/MVIC color camera on July 14 at 11:11 AM UTC, from a range of 22,000 miles (35,000 kilometers). This image was presented by Will Grundy of the New Horizons’ surface composition team on Nov. 9 at the Division for Planetary Sciences (DPS) meeting of the American Astronomical Society (AAS) in National Harbor, Maryland.
