Comments Off on ESA 3D prints extraterrestrial bricks with concentrated sunlight and moondust

The European Space Agency (ESA) is getting in on the 3D-printing fun with extraterrestrial materials. They used simulated lunar material and the sun’s heat to print bricks that are as strong as gypsum . Their project demonstrates how lunar explorers could one day use a similar method to construct Moon colonies. Future travelers to both the Moon and Mars could use locally-sourced materials to build habitats. Recently University of California, San Diego engineers funded by NASA were able to create super-strong bricks with simulated Mars dirt, and now ESA scientists have been able to use dust with similar composition and grain size as the material on the moon to 3D print bricks. Related: Scientists create super-strong bricks from Mars-like soil Materials engineer Advenit Makaya said they cooked successive layers of moondust 0.1 millimeters thick in a solar furnace at temperatures of 1,000 degrees Celsius – or 1,832 degrees Fahrenheit. The team can finish a 7.9 by 3.9 by 1.1 inch brick in about five hours. The solar furnace is located at the DLR German Aerospace Center , a place you may be familiar with because they recently built the world’s largest artificial sun . The bricks will now go through extensive mechanical testing. They’re not perfect yet; for example, some have warped at their edges because the center cools slower than the edges. Advenit said they’re looking into ways to manage the warping, “but for now this project is a proof of concept, showing that such a lunar construction method is indeed feasible.” The European Union’s Horizon 2020 program will back a follow-up project, RegoLight , which aims to develop 3D printing technology to shape lunar regolith, or the “loose layer of dust, soil, and broken rocks on the Moon surface.” Advenit said the recent ESA project occurred in normal atmospheric conditions, but RegoLight will attempt to 3D print with moondust in the high temperature extremes and vacuum conditions you’d find on the Moon.

Earth’s atmosphere is leaking 90 tons of material every day

Comments Off on Earth’s atmosphere is leaking 90 tons of material every day

Earth has sprung a leak. Every day, 90 metric tons of matter leaks from Earth’s upper atmosphere into space. This sounds scary, but in total the atmosphere weighs about five quadrillion metric tons, so we have a lot of atmosphere to work with. Still, scientists are paying attention to the leak, because it could help us understand what makes a planet habitable.

New Hubble images finally reveal what the Crab Nebula hides in its core

Comments Off on New Hubble images finally reveal what the Crab Nebula hides in its core

Legions of scientists have studied and taken images of the Crab Nebula — in fact, it’s one of the most-studied object in space. But until now, astronomers have never been able to glimpse the object at the heart of the massive gas cloud. Until now. New Hubble images have revealed a fast-moving neutron star at the heart of the nebula. The Crab Nebula , which lies 6500 light years away from Earth, was created by a supernova long ago. A massive star in the Taurus constellation exploded at immense speeds, creating the expanding cloud of gas we see today, called a supernova remnant. Most images of the nebula focus on the intense colors and shapes of the nebula’s outer filaments, but what’s going on in the heart of the cloud may be even more interesting. It turns out that when the original star making up the nebula exploded, it left behind its inner core, a strange and exotic object known as a neutron star . While this star has roughly the same mass as our sun, it only measures a few tens of kilometers across — an incredible density made possible by the compression of the subatomic particles that make up the star. Until now, it’s been almost impossible to capture this star’s movement on camera due to its high speed: it rotates approximately 30 times per second. Related: NASA captures shockwave of a massive supernova for the first time ever To capture the neutron star, astronomers used the Hubble Space Telescope to take three high-resolution images about 10 years apart each. Those images were combined together to create a sort of time-lapse showing bright “ripples” in the center of the nebula; bands of light are actually caused by the radiation of electrons spiraling through the star’s magnetic field at nearly the speed of light. This isn’t the first time the Crab Nebula has made history . The supernova explosion that created the cloud was one of the first such events in recorded human history.  In the year 1045, astronomers in Japan and China noticed a bright new star in the night sky said to be nearly as bright as the moon. That bright light was caused by the distant explosion, and over the next several years it gradually faded until it was invisible to the naked eye. Luckily, it’s still possible to see with the help of the Hubble . Via Gizmodo Images via ESA/Hubble

Comments Off on The ESA tests Kombucha resilience on an unprotected journey through space

Samples of kombucha are currently attached to the outside of the International Space Station, exposed to the harsh elements beyond our protective atmosphere. At face value, this may sound downright strange, yet The European Space Agency has its reasons for testing whether the yeast and bacteria in Kombucha can survive an unprotected journey through space.

Comments Off on Scientists just discovered the building blocks of life on a comet

Incoming data since last year’s landing on comet 67P has revealed the presence of organic compounds, which has the scientific community buzzing about the larger implications. Comets really could be carrying the “building blocks” of life. The European Space Agency landed the Philae probe back in November, 2014, and the information streaming back to Earth is proving to be quite interesting.

Comments Off on Mind-blowing Photographs of Earth Taken From Space

Updated weekly, ESA’s Observing the Earth archive consists of thousands of photographs that date back to 2005. These Earth Observation images capture wide-angle snapshots of various landscapes with a precision that could only be matched by an “army of ground-level observers.” With incredible accuracy, these satellite images can capture environmental changes to the landscape in real-time, from a creeping blanket of air pollution to the catastrophic damage wrought by an earthquake. This long-term monitoring provides an objective assessment of human activity’s global impact and even the effects of climate change . Although satellite acquisitions are often depicted as static images, they are actually comprised of layers of workable digital data. Over time, the images collected can reveal the unfolding scale of environmental destruction and weather mapping and help contribute to environmental activism and identification of at-risk areas to natural disasters.

Comments Off on UK Politicians Call For Ban On Arctic Drilling Due To Safety Concerns

The UK’s Environmental Audit Committee has released a report titled “Protecting the Arctic” in which Members of Parliament call for a halt on oil drilling in the region until several concerns are addressed. The concerns include the need for a pan-Arctic oil spill response standard, stricter financial liability regimes for oil and gas operations that require companies to prove that they can meet the costs of cleaning up, and an internationally recognized environmental sanctuary established in at least part of the Arctic.

Comments Off on Arctic Sea Ice to Hit Record Low This Month According to US National Snow and Ice Data Center Reports

Last week we reported that The European Space Agency’s CryoSat 2 probe had completed its 18-month-long mission and revealed that over 900 cubic kilometers of summer sea ice had disappeared from the Arctic ocean over the past year. That’s a loss 50% greater than figures predicted by most polar scientists. Now scientists at the US National Snow and Ice Data Center have stated that Arctic sea ice is set to hit a record low by the end of this month.
