Stars shine above as a plume rises from the Halemaumau crater, illuminated by glow from the crater's lava lake, within the Kilauea volcano summit at the Hawaii Volcanoes National Park on May 9, 2018 in Hawaii Volcanoes National Park, Hawaii. The U.S. Geological Survey said a recent lowering of the lava lake at the crater “has raised the potential for explosive eruptions” at the volcano. The volcano has spewed lava and high levels of sulfur dioxide gas into communities, leading officials to order 1,700 to evacuate. Officials have confirmed 26 homes have now been destroyed by lava in Leilani Estates. (Photo by Mario Tama/Getty Images)

This undated photo provided by NOAA in May 2018 shows aurora australis near the South Pole Atmospheric Research Observatory in Antarctica. When a hole in the ozone formed over Antarctica, countries around the world in 1987 agreed to phase out several types of ozone-depleting chemicals called chlorofluorocarbons (CFCs). Production was banned, emissions fell and the hole shriveled. But according to a study released on Wednesday, May 16, 2018, scientists say since 2013, there’s more of a banned CFC going into the atmosphere. (Photo by Patrick Cullis/NOAA via AP Photo)





In this image released on Wednesday, July 11, 2018, the Milky Way, visible in the skies above the Gran Telescopio Canarias at the Roque de los Muchachos Observatory on the island of La Palma in the Canaries, Spain. On July 27th Mars will be nearing the closest it's been to Earth in 15 years. This event, occurring in parallel to the longest lunar eclipse of the 21st century, creates a unique experience offered to six guests on Airbnb to visit the telescope and view the night sky from one of the best stargazing spots on the planet.
