Before the sun set on the White House South Lawn on Monday night, President Barack Obama called two astronauts orbiting the Earth onboard the International Space Station.

The extra-long distance phone call was made as part of the White House’s second Astronomy Night, which saw 11 different astronauts and 300 students descend on 1600 Pennsylvania Avenue’s South Lawn to stargaze among notables like Bill Nye and Ahmed Mohamed, the Texas student arrested at his school for making a homemade clock.

As students studied the stars via heavy duty telescopes, their actions were buffeted by the president’s words urging participation in Science, Technology, Engineering and Mathematics education programs. “We need to inspire more young people to ask about the stars,” the president said.

Then the president got in on some of the moonlit fun himself. According to USA Today, he was given a lecture on the moon by Agatha Sofia Alvarez-Bareiro, a high school senior from New York City.

Here’s POTUS in fine stargazing form:

The president also met with Ahmed Mohamed, the Texas student who was arrested for bringing a homemade clock to school that authorities suspected was an explosive device. Obama invited Mohamed to the White House last month, and made good on his promise during Astronomy Night.

Several of the NASA astronauts present at the event also answered some questions about their experiences in outer space. From the left hand side of the photo below, you’ll see Sunita Williams, Eric Boe, Robert Behnken and Douglas Hurley participating in a panel moderated by Cristin Dorgelo, Chief of Staff at the White House Office of Science and Technology Policy.

Selfies seemed to abound across much of the South Lawn last night, at least when students weren’t stargazing or listening to the president speak about the importance of science.

Here’s astronaut Cadie Coleman getting silly with some students.

The great Bill Nye joined in on the festivities as well, and snapped this brilliant selfie in front of the White House:

The first White House Astronomy Night took place in 2009, but due to what looks like unprecedented enjoyment shared by all at Monday’s event, we suspect it will be in popular demand for years to come.

SpaceX is gearing up to send humans into space for the first time. On Monday, CEO Elon Musk confirmed a report that claimed NASA estimates the firm will be ready for people-carrying space adventures as early as April of next year. While a good sign for the company’s Mars mission, a successful human test flight would also enable a new method of sending people to the International Space Station.

It’s easy to live next to someone for a really long time without learning much about them, but sometimes our neighbors can turn out to be a lot more interesting than we assume, especially when they’re our galactic neighbors. It might turn out that they have great stories to tell — or that they’re the oldest galaxies in the freaking universe. And hey, wouldn’t you know it, that’s exactly what happened when an international team of astronomers took a closer look at the faint galaxies surrounding our galaxy, the Milky Way.

Despite a few delays and technical glitches, the Parker Solar Probe has finally seen liftoff. The ambitious mission to become the first spacecraft to enter the sun’s corona is now underway and the physicist for whom the spacecraft was named was able to watch the historic launch.

Before the Parker Solar Probe was launched aboard the Delta IV Heavy rocket at 3:31 a.m. Eastern on Sunday, it had already achieved many firsts in innovation, such as its heat shield, the Thermal Protection System. However, it’s also a cultural first for NASA, whereby the mission was named after a living scientist for the first time in the space agency’s history. This created an opportunity for Dr. Eugene Parker to see his namesake launch into space and discuss the experience.

When you imagine an Egyptian mummy, you probably picture the embalmed body of a pharaoh, carefully wound in long strips of linen and laid in an ornate sarcophagus. But the mummies of an earlier age weren’t laid to rest in such decadence, suggesting to the scientists who found their bodies in shallow pits that they were preserved by chance, sand, and air. This “natural preservation” theory, however, might be laid to rest by a study published Thursday in the Journal of Archeological Science. Prehistoric Egyptian mummies, the authors say, were also treated with care.

In modern society, you can be lazy and not face much consequence. Don’t want to cook? Order Seamless. Don’t want to move? Call a Lyft. But according to a controversial new study, the same could not be said for Homo erectus, an ancient relative of our species. In the study, scientists claim that H. erectus went extinct because it existed in a constant state of meh.
