Just how big is your average comet? Experts say that the average comet has a nucleolus that reaches out to about 6 square miles, That makes the comet that the European Space Agency's Rosetta spacecraft just recently chased down up-to three times smaller than some of its brethren. Those figures truly don't give this enormous space rock justice. Now, a new photo has been circulating the twittersphere that has people in awe of what they thought was a "tiny" comet.
Just last week, an astronaut aboard the International Space Station (ISS) drove a car-sized rover back on Earth during a demonstration of the European Space Agency's (ESA) latest advancements in remote communication software.
After playing an otherworldly game of cat-and-mouse for more than a decade, the European Space Agency's (ESA) Rosetta spacecraft has finally caught up to its comet quarry, making history with a first meeting at breakneck speeds of more than 3,400 mph (55,000 km/h.)
The European Space Agency's (ESA) Rosetta spacecraft is only five days away from reaching its comet quarry after beginning a chase that started in 2004. Earlier this month, the craft was able to measure the temperature of the comet for the first time.
Astronauts aboard the International Space Station finally flight tested their prototype flying robot assistants last Friday, setting the stage for an international robot programming competition that is slated to officially begin this fall.
Training astronauts and caving specialists will soon descend into the depths of the Earth in order to train for future space missions, according to the European Space Agency (ESA).
New images from the European Space Agency's (ESA) comet-chasing Rosetta spacecraft have revealed that its quarry is a fairly irregular-shaped chunk of space ice and rock.
The NOAA and US Fish and Wildlife Service (USFWS) as of Thursday officially granted the threatened loggerhead sea turtle a vast expanse of critical habitat along the Atlantic and Gulf coasts - possibly the biggest protective move in US history.
The European Space Agency's (ESA) Rosetta spacecraft is closing in on its asteroid "prey" and scientists are beginning to notice some nervous sweating. Rosetta and NASA-made instruments are already detecting water vapor dripping from the comet even 217,480 miles (~350 000 km) away.
In an effort to secure and eliminate potentially threatening space debris orbiting around Earth, the European Space Agency (ESA) is considering resorting to harpooning these tumbling satellites, according to their press release.
The European Space Agency's (ESA) Swarm mission recently revealed Earth's weakening magnetic field, which is necessary to protect our planet from bombarding cosmic radiation and charged particles.
When the comet Shoemaker-Levy 9 (SL9) hit Jupiter in the summer of 1994, it may have left more than visible scars on the Jovian surface, according to a new study published in Astronomy and Astrophysics.
NASA has joined the European Space Agency's (ESA's) Euclid mission to study dark matter and dark energy.
