The Boomerang Nebula is the coldest location in the known universe at roughly 2 degrees colder than empty space! This nebula is the result of the death of a red giant star, and the extreme temperature is caused by the rapid expansion of the nebula. According to thermodynamics, if you expand a gas you cool a gas (just try using one of those compressed air cans for cleaning electronics). However, according to astronomers, a single star's death could not account for a strong enough wind to create

The Total Solar Eclipse of 2017 that crossed the United States garnered international attention. Here in Canada we were treated to a beautiful partial solar eclipse, and the Canada Aviation and Space Museum attracted thousands of visitors to watch. Here NASA has published some of the ways the eclipse was watched, from the ground and from space. My favourite is the above picture because it has the Sun, which is 150 million kilometres away, the Moon, which is 400,000 kilometres away, and the

NASA's Cassini-Huygens mission has begun its final mission phase, making its first dive between the planet Saturn and its rings. It is the only craft to ever make that plunge. Check out some of the amazing images it took as it went through, including the north pole hexagonal vortex.

Human's have been launching satellites into space since 1957, and now the current number of objects in orbit larger than 10 cm is about 23,000. The growing number poses a real threat to the future of space exploration. Humanity will need to solve this problem moving forward, and ideas are currently being discussed.

Two NASA Satellites were used to create this image of the straight of Gibraltar: Suomi NPP, and Aqua. The images were processed and combined to highlight the blooms of phytoplankton in the area, which has been caught up in the turbulent ocean currents moving through the strait.

Astronomers from Keele University, the Max Planck Institute for Astronomy, and others, have discovered the first atmosphere around an Earth-sized planet. The planet, GJ1132b is about 1.4x Earth's diameter and 39 light years away from us. Currently there are over 3000 known planets orbiting stars other than the Sun, but only a handful of which have been confirmed to have atmospheres, and all of which are massive Jupiter-sized planets. In the ongoing quest to find a planet similar to Earth, this
