Herschel Telescope Runs Out of Coolant, Ends Mission

The European Space Agency (ESA) today announced that the Herschel space observatory has run out of liquid helium coolant. The coolant is necessary to cool the telescope’s instruments to near absolute zero. Herschel’s ground station in Western Australia this afternoon found that the temperature in all of the telescope’s instruments is rising, confirming that the helium has run out. The …

Water on Jupiter Linked to Shoemaker-Levy Impact

It appears that the mystery of how water got into the atmosphere of Jupiter has finally been solved. The European Space Agency (ESA) today announced that the water in the Jovian planet’s upper atmosphere has been linked to the 1994 Shoemaker-Levy 9 impacts. The comet Shoemaker-Levy 9 broke up and collided with Jupiter in July of 1994. The week-long event, …

NASA Measures Fast-Spinning, Supermassive Black Hole

NASA today revealed that it has teamed up with the European Space Agency (ESA) to, for the first time, measure the spin rate of a supermassive black hole. Using NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) and the ESA’s XMM-Newton, astronomers were able to observe the black hole that lies at the center of the galaxy NGC 1365. The object was …

Russian Meteor Blast Explained by NASA [VIDEO]

On February 15, when the world’s astronomers were busy watching Asteroid 2012 DA14 make a close flyby of Earth, a different space rock entered Earth’s atmosphere and broke up over Chelyabinsk, Russia. The shockwave following the meteor’s destruction shattered windows and damaged property throughout the Russian town. Later that week, the European Space Agency (ESA) announced that it was studying …

Arctic Sea Ice Volume Declining, Shows Satellite Data

A new European Space Agency (ESA) study has shown that Arctic sea ice has declined significantly since 2003. The study, published recently in the journal Geophysical Research Letters, has confirmed that Arctic ice volume is declining, rather than just sea ice coverage. The paper shows that the ice has declined by (36%) during the fall months and 9% during winter …

Space Laser Could Detect Counterfeit Foods, Past Life on Mars

The European Space Agency (ESA) today revealed that a laser developed to measure carbon on Mars could soon be used to detect counterfeit food. The device, called a laser isotope ratio-meter, was developed from bulkier laser techniques that needed samples to be collected and brought to them. The new device, developed by the Rutherford Appleton Laboratory (RAL) in England, is …

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 …

The First Moon Base May Be Constructed With 3D Printers

A moon base has always been the pipe dream of space agencies around the world, but the prohibitive cost always ensured that such a move would never happen anytime soon. That all may be changing sooner than later as the European Space Agency has an idea that’s just crazy enough to work. The ESA announced on Thursday that it’s hard …

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 …
