Antarctic Ozone Could be Returning, Shows New Images

New satellite imagery has shown that the hole in the ozone layer over Antarctica is shrinking. In 2012, the hole was the smallest it has been in the past ten years. The images were taken by the European Space Agency’s (ESA) MetOp satellite, which has a ozone sensor. The satellite monitors atmospheric ozone over the Antarctic. Since the 1980s, the …

Space Life Weakens Immune Systems, Shows Study

A new study performed aboard the International Space Station (ISS) has shown that being in space weakens astronauts’ immune systems. Researchers hope the findings can help prevent disease for those of us still on the planet. European Space Agency (ESA) astronaut Thomas Reiter performed the experiments while on the ISS, as seen in the video below. Human immune cells were …

Late Planet-Forming Star Spotted by Herschel

NASA and the European Space Agency’s (ESA) Herschel Space Telescope has spotted a planet-forming star that wasn’t thought to be possible. The star, named TW Hydrae, is estimated to be 10 million years old – older than the age at which stars are thought to be able to produce planets. However, the star still has an accretion disc massive enough …

Comet-Like Ionosphere Seen on Venus

New observations of Venus have shown that the planet’s ionosphere on its night side resembles a comet’s tail. The observations were made by the European Space Agency’s (ESA) Venus Express satellite. The ionosphere is the region of electrically charged gas high in a planet’s atmosphere. The shape and density of an ionosphere are determined, in part, by the internal magnetic …

NASA Joins Euclid Dark Universe Mission

NASA announced this week that it has joined the European Space Agency’s (ESA) Euclid mission. The mission will investigate dark matter and dark energy throughout the universe. In 2020, the mission will launch the Euclid space telescope, which will spend six years mapping and measuring as many as 2 billion galaxies that cover one-third of the sky. The hope is …

New Satellite Search and Rescue System Turned On

The European Space Agency (ESA) today announced that it has switched-on a search and rescue (SAR) package on its Galileo navigation satellites. The milestone is a “major” expansion of the Cospas-Sarsat (Space System for the Search of Vessels in Distress and Search and Rescue Satellite-Aided Tracking) network, which receives distress calls from air and sea vessels. “At this stage, our …

Doomsday Asteroid Deflection Mission Tests Concepts

The European Space Agency (ESA) today announced that it is appealing for research ideas that could help develop a future mission to deflect life-threatening asteroids. It is asking for both ground and space-based ideas to improve scientist’s understanding of high-speed collisions between man-made and natural objects. No asteroids are currently on a collision course with Earth (though some are coming …

“Doomsday” Asteroid Won’t Hit Earth in 2036

Earlier this week, astronomers with the European Space Agency (ESA) announced that they were collecting data on the asteroid Apophis as it made its most recent approach to Earth. The data was, among other things, meant to narrow the prediction as to whether the asteroid might impact the Earth in 2036. Now, NASA has announced that Apophis will not be …

Vega Asteroid Belt Suggests Multiple Planets

Astronomers this week announced that they have discovered what could be an asteroid belt around the star Vega. NASA‘s Spitzer space telescope and the European Space Agency’s (ESA) Herschel Space Observatory were used to observe the star, which is the second brightest in the northern sky. Vega was found to have an astroid belt-like band of debris in both a …

Asteroid Apophis Approaches Earth, 2036 Impact Probability Still Uncertain

Over the past weekend, astronomers used the European Space Agency’s (ESA) Herschel Space Observatory to image an asteroid that will be giving the Earth a near-miss in 2029. The asteroid, named Apophis, was thought to have a 2.7% chance of striking the Earth in 2029 when it was discovered in 2004. New observations have ruled out an impact, but the …

Cassini Spots “Mini Nile River” on Saturn’s Titan

The Cassini probe orbiting Saturn and its moons has photographed what the European Space Agency (ESA) is calling a “miniature extraterrestrial version of the Nile river” on Saturn’s moon Titan. The formation is a river valley on the the moon’s surface that runs for over 400 km (248 miles) from its source to a large sea. The radar image is …

Astronomers Reveal Unseen Starburst Galaxies

Astronomers announced today that have characterized hundreds of previously unseen starburst galaxies. The starburst galaxies, which produce hundreds of stars each year, reveal that high star-formation rates have been the norm for much of our universe’s history. Using the European Space Agency’s (ESA) Herschel space observatory and W.M. Keck telescopes, astronomers measured the temperature, brightness, and star formation rate of …
