Tell us about something that happened today in history, and make it relate to current science.

Thanksgiving is upon us, and once again, the centerpiece of the traditional holiday meal is a dinosaur. Eat up and 'Happy Thanksgiving'!
A total solar eclipse was visible across the extreme north of Australia yesterday giving residents, tourists, and eclipse-chasing scientists the thrill of a lifetime. Here’s a timelapse and informational video of the event. Total solar eclipses occur about twice each year but since the Earth is 70 percent water, they often happen in remote, unpopulated locations. But remember folks, in less than five years, the Moon’s shadow will sweep across the mid-section of the United States when a total solar eclipse takes place on August 21, 2017. Whatever you do, do not miss it. It is truly something amazing to witness live.
Courtesy Mark RyanNational Fossil Day is finally here. The official website calls it "a celebration organized to promote public awareness and stewardship of fossils, as well as to foster a greater appreciation of their scientific and educational value."
I'm a big fossil fan year round but I'm particularly happy today because I won first place in the NFD's Art & Photo Contest! The theme this year was "Careers in Paleontology". My entry, pictured at right, is a nod to paleoart and features a new "dinosaur" species (Bryocrinoidosaurus decorahi) created using invertebrate fossils found in Minnesota. You can view all the winning entries here.
National Fossil Day is planned and promoted by the National Park Service through partnerships with professional organizations, government agencies, and other science-related groups such as the American Geosciences Institute, the National Earth Science Teachers Association and the Paleontological Research Institution.
The Science Museum of Minnesota celebrates National Fossil Day this coming Saturday, October 20, from 1pm to 4pm. Everyone is invited to join in on the celebration of fossils!
Felix Baumgartner, the Austrian skydiver attempting to break several frreefall records, has lifted off from Roswell, New Mexico and is ascending into the stratosphere and beyond as I write. The helium balloon that's lifting him upward is, right now, nearing 100,000 feet at a rate of about 15 feet/second. He hopes to reach 120,000 and then leave the capsule for about a 10 minute jump back to Earth. Half of that time will be spent in freefall. That's all I know. You can watch a delayed webcast of it at the BBC website.
The SpaceX rocket lifted off today from a launch pad at Cape Canaveral, Florida, becoming the first commercial flight to the International Space Station and marking the beginning of a new era of space exploration. Read about it here.
Courtesy Mark RyanTonight there will be what is known as a Blue Moon. It's not an astronomical event but rather a calendrical one and occurs when two full moons happen in the same month. This kind of thing happens about every 2.7 years and doesn't have anything to do with the color of the moon. You won't see any blue tinge on the night orb tonight unless a nearby volcano has spewed ash laden with cobalt into the atmosphere. The first full moon this month was back on August 2nd. The last blue moon we had was in December of 2009 and the next won't happen until July of 2015, so you might as well out there and enjoy this one. This kind of event only happens once in a blue moon.

In 1945, a US warplane dropped the first atomic bomb on the Japanese city of Hiroshima. Three days later the US dropped another nuclear bomb on the city of Nagasaki. The bombings led to Japan's surrender and the cessation of World War II. I seem to post about this each year, so you can find more details here.

Some thirty-eight years later, in July of 1969, Armstrong and two other US astronauts, Buzz Aldrin, and Michael Collins traveled to the Moon in the Apollo 11 spacecraft. As Collins orbited the Moon in the command service module (CSM), the other two crew members descended to the surface in the lunar module (LM). After successfully landing on the Sea of Tranquility, Armstrong climbed down the LM ladder and took his historic first step onto the surface at 2:56 UTC July 21, 1969. Aldrin joined Armstrong about 20 minutes later, and the two astronauts spent the next 2-1/2 hours of the mission investigating the lunar surface, setting up science-gathering equipment, and collecting rock and soil samples, before blasting off the surface to rejoin Collins for the return trip to Earth.
