On Friday, Google Celebrated The 300th Birthday Of Dorothea Christiane Erxleben, Germany’s First Female

On Friday, Google celebrated the 300th birthday of Dorothea Christiane Erxleben, Germany’s first female doctor and advocate for women’s rights in the early 18th century. While it took a royal decree for her to get a medical license, her story of passing the test is quite impressive.

But lightyears are distance so how can you be a distance to late?

Great Scott, it’s Back to the Future Day – Oct. 21, 2015

What would a time traveler from 1985 discover about NASA today?

It’s Back to the Future Day, the date in the second film that Marty and Doc traveled to in the future. When they arrived in 2015, it looked much different than today’s reality. Although we may not have self-drying jackets or flying cars, we do have some amazing spacecraft and technologies that were not around back when the film was made.

For example, in 1985 we did not have the capability to capture an image like this of our Earth. This full-Earth view captured Monday (10/19/15) by our camera on the Deep Space Climate Observatory, or DSCOVER, was not previously possible. The DSCOVR mission captures a daily sequence of images that show the Earth as it rotates, revealing the whole globe over the course of a day. These images will allow scientists to study daily variations over the entire globe in such features as vegetation, ozone, aerosols and cloud height and reflectivity.

So, we might not be cruising down the street on hover boards, but the movies didn’t get it all wrong in terms of how advanced we’d be in 2015.

When you were a kid, what technologies did you dream we’d have in the future that we may or may not have today? Here’s what two astronauts said:

NASA is much different than it was in 1985. Could we have dreamed these amazing accomplishments that have changed our world and understanding of the universe?

1. “There will be an orbiting laboratory where astronauts from around the world will live and work together.”

When Back to the Future II was set, the International Space Station didn’t exist yet. The first piece of the space station was launched in 1998, and the first crew arrived in 2000. Since November 2000, the station has been continuously occupied by humans.

2. "We will find planets orbiting in the habitable zone of a star, and possibly suited for life.“

The first exoplanet, or planet orbiting around a star, was found in 1995. Since then, we’ve discovered around a dozen habitable zone planets in the Earth-size range. While we aren’t able to zoom in to these planets that are light-years away, we’re still closer to finding another Earth-like planet in 2015 than we were in 1985.

3. “Mars will become more populated.”

No, not by humans…yet. But, since the release of Back to the Future II, Mars has become a bit more populated with rovers and orbiters. These scientific spacecraft have played an important role in learning about the Red Planet. We currently have six missions at Mars. With the most recent news of liquid water on the surface of Mars, we can look forward to future missions returning even more data and images. The historical log of all Mars missions, both domestic and international can be found HERE.

4. “We will launch a telescope into orbit that’s capable of looking at locations more than 13.4 billion light years from Earth.”

When Back to the Future II was released, our Hubble Space Telescope had not yet launched into orbit – something that wouldn’t happen until April 1990. Since then, Hubble has made more than 1.2 million observations, and has traveled more than 3 billion miles along a circular low Earth orbit. For updates on Hubble’s findings, check HERE.

Astronomy Night at the White House

NASA took over the White House Instagram today in honor of Astronomy Night to share some incredible views of the universe and the world around us. Check out more updates from the astronauts, scientists, and students on South Lawn.

Here’s a nighttime view of Washington, D.C. from the astronauts on the International Space Station on October 17. Can you spot the White House?

Check out this look at our sun taken by NASA’s Solar Dynamics Observatory. The SDO watches the sun constantly, and it captured this image of the sun emitting a mid-level solar flare on June 25. Solar flares are powerful bursts of radiation. Harmful radiation from a flare can’t pass through Earth’s atmosphere to physically affect humans on the ground. But when they’re intense enough, they can disturb the atmosphere in the layer where GPS and communications signals travel.

Next up is this incredible view of Saturn’s rings, seen in ultraviolet by NASA’s Cassini spacecraft. Hinting at the origin of the rings and their evolution, this ultraviolet view indicates that there’s more ice toward the outer part of the rings than in the inner part.

Take a look at the millions of galaxies that populate the patch of sky known as the COSMOS field, short for Cosmic Evolution Survey. A portion of the COSMOS field is seen here by NASA’s Spitzer Space Telescope. Even the smallest dots in this image are galaxies, some up to 12 billion light-years away. The picture is a combination of infrared data from Spitzer (red) and visible-light data (blue and green) from Japan’s Subaru telescope atop Mauna Kea in Hawaii. The brightest objects in the field are more than ten thousand times fainter than what you can see with the naked eye.

This incredible look at the Cat’s Eye nebula was taken from a composite of data from NASA’s Chandra X-ray Observatory and Hubble Space Telescope. This famous object is a so-called planetary nebula that represents a phase of stellar evolution that the Sun should experience several billion years from now. When a star like the Sun begins to run out of fuel, it becomes what is known as a red giant. In this phase, a star sheds some of its outer layers, eventually leaving behind a hot core that collapses to form a dense white dwarf star. A fast wind emanating from the hot core rams into the ejected atmosphere, pushes it outward, and creates the graceful filamentary structures seen with optical telescopes.

This view of the International Space Station is a composite of nine frames that captured the ISS transiting the moon at roughly five miles per second on August 2. The International Space Station is a unique place—a convergence of science, technology, and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. As the third brightest object in the sky, the International Space Station is easy to see if you know when to look up. You can sign up for alerts and get information on when the International Space Station flies over you at spotthestation.nasa.gov. Thanks for following along today as NASA shared the view from astronomy night at the White House. Remember to look up and stay curious!
