There are almost one million asteroids and comets in our solar system. And every single one of them (we think) formed here, within our solar system, alongside the planets just over 4.5 billion years ago. However, in the summer months of 2017, an object not borne from the Solar System made a silent entrance, whipped around the Sun in September 2017, and started heading out again, never to return. This object, now named ‘Oumuamua, was the first asteroid discovered from outside the solar system

The first exosolar planet (a planet orbiting a star other than the Sun) was discovered in 1995, and since then humans have found over 3600 planets outside of our solar system. Some of those found are orbiting not one star like we do, but two stars. For example, stars Kepler-35A and 35B orbit each other, but a planet Kepler-35b, orbits both of them. This is much more like the fantasy word Tatooine in the space epic Star Wars than our own planet Earth. In A New Hope, we see young Luke Skywalker

A new company called Earth-i has announced it will be launching a constellation of satellites into Earth's orbit that will download "fast-turn-around pictures and colour video of the planet's surface."

When you read a scientific story in a popular blog or magazine, many times you will see the caveat "artist interpretation" next to some of the accompanying images. This as a gross undersell of the time, effort, and most important, accuracy, that goes into developing the renders. While we don't know what a black hole or an exoplanet looks like, it is important to attempt to visualize them, and to do it as accurately as possible. This video is an interview with two people who are responsible for

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.

A short description of the upcoming Grand Finale of the Cassini Spacecraft. Over the next 5 months, Cassini will make 22 plunges between Saturn's rings and the planet itself. No craft has ever been that close. During this final phase, Cassini will make close up measurements of the rings for the first time, image the planet's cloud-tops in unprecedented detail, and even answer long-standing questions like: how fast does Saturn actually rotate? It's going to be a very interesting 5 months.

On April 12, 1961, Yuri Gagarin became the first human to venture into space. At just after 9 am local time at the Baikonur Cosmodrome in Kazakhstan, Gagarin launched into low earth orbit, completed a full orbit in 108 minutes, and returned safely. This achievement not only firmly set the Soviet Union has the leader in space technology at the time, but marked the beginning of the human exploration of space. Internationally, April 12 is now "Yuri's Night," an evening of celebration meant to

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.

NASA recently released a more in-depth look at its missions beyond low-Earth orbit. The whole vision is being dubbed the 'Journey to Mars:' a 2 phase program designed to step further and further way from Earth. The first phase will place a space station in lunar orbit. The second phase will see humans launching off to the red planet.
