Comments Off on Mars is emerging from a 400,000 year-old ice age

A new study has found that Mars is emerging from an ice age that ended about 400,000 years ago. While scientists have long believed that the planet has undergone several rounds of ice ages in the past, there have been few physical measurements to actually prove the theory. Now, the journal Science has published the first map of the red planet’s ice deposits, along with confirmation of the planet’s icy past. Just like Earth, Mars undergoes cycles of planetary warming and cooling, but this has more to do with the “tilt” of the planet than anything else. While Earth’s axis is tilted 23.5 degrees and remains relatively stable over time, Mars has an axis that shifts from 10 to 40 degrees. The wobble in Mars’ orbit is due to two factors: one, it doesn’t have a large moon like we do to stabilize it, and two, its proximity to Jupiter allows it to be tugged by the larger planet’s gravity. When the planet is tilted to an extreme degree, its poles receive more sunlight and its equator cools, causing an ice age. Researchers used NASA’s Mars Reconnaissance Orbiter to gather radar images of the red planet’s ice deposits, allowing them to look for signs of erosion and other hints of how the ice on Mars has formed and redistributed over time. These images confirmed that Mars’ last ice age ended about 400,000 years ago — which, in planetary terms, is not as long as it seems.

But it also may offer scientists a better glimpse into the science behind climate change on our own planet. While global warming on Earth is due to greenhouse gas emissions , not the wobble of the Earth’s pole, Mars is the most similar planet to our own in the Solar System and could help us better understand the physics behind climate change in an environment without human interference. + Science Via The Verge Images via NASA/JPL-Caltech/MSSS

1. Light and darkness contrast in Daniel Libeskind’s Jewish Museum Berlin One of the most moving memorial buildings ever created, Daniel Liebeskind ‘s Jewish Museum in Berlin, utilizes architecture to take visitors on a journey through some of humanity’s darkest moments during the Holocaust, when millions of people were murdered by the Nazis. From above, the museum appears to be an ” exploded Star of David .” Sharp angles and zigzagging hallways take visitors on a contemplative journey to the Holocaust Tower, Garden of Exile, and Stair of Continuity. The strong design of the museum stands out from other buildings nearby, bringing attention to its important purpose. 2. Reflecting pools allow contemplation at the National 9/11 Memorial by Michael Arad Right where the Twin Towers used to stand in New York City, Michael Arad designed the National 9/11 Memorial to capture the enormous loss and invite visitors to reflect. Carved in bronze, the names of those who died on September 11 surround two massive reflecting pools with the biggest man-made waterfalls in America. The simplicity of the memorial contrasts with the grandiose scale, evoking the sense that each loss is incredibly personal while remembering so many died and were impacted that day. 3. Earthquake debris utilized in Ishi-no-kinendo Memorial by Koishikawa Architects In the aftermath of Japan’s 2011 earthquake , 18,000 people died or went missing. Tokyo’s Koishikawa Architects created a memorial, called Ishi-no-kinendo , from the rubble of a city hit hard on Japan’s east coast. Lines etched into mirrored stainless steel on top of the monument point mourners to the other locations impacted by the earthquake so they can grieve the loss of loved ones around the country. Since the earthquake struck in the spring, a nearby cherry tree that blossoms that time of year adds natural beauty to the monument. 4. Axel de Stampa and Sylvain Macaux’s Qatar World Cup Memorial tower is scalable Over 1,000 migrant workers in Qatar have already perished in the lead up to the 2022 World Cup Stadium . Architects Axel de Stampa and Sylvain Macaux imagined a scalable tower commemorating those people as part of their experimental 1 Week 1 Project effort. Their Qatar World Cup Memorial would draw attention to the country’s reprehensible labor practices, and could grow as more die to build the stadium under conditions some have described as akin to slavery. They said if nothing changes for these workers, the memorial might stretch close to a mile in the sky. 5. Chapel of Reconciliation by Rudolf Reitermann and Peter Sassenroth on old no-man’s-land Architects Rudolf Reitermann and Peter Sassenroth utilized rammed-earth architecture to create a minimalist chapel between what was once East Berlin and West Berlin. They erected their Chapel of Reconciliation on the site of a former church torn down in 1985 for ” security measures .” Some materials from the demolished church were incorporated in the new chapel in remembrance of what was lost when Berlin was divided. The building also usher in a new era through the use of ” sustainable natural methods ” in its construction. 9/ll Memorial image © Amanda Silvana Coen for Inhabitat; other images via Daniel Libeskind , Koji Fujii/Nacasa & Partners , 1 Week 1 Project , and jaime.silva on Flickr

Tom Dixon transforms a 17th-century London church into a chic co-working space

The motivation behind the project began with Baughen’s desire to make the church more available to the daytime residents and creative workforce of Clerkenwell, an area in central London. The temporary intervention also gave Dixon the opportunity to display his new lighting and furniture products against a stunning historic backdrop with soaring ceilings and huge stained glass windows. “As the Church evolves and adapts to the new conditions of the 21st century, the opportunity of opening up to new audiences and unexpected collaborations becomes a necessity,” says Dixon. “For the design audience and the more permanent residents of Clerkenwell, we hope that a contemplative and spiritual space becomes more comfortable and accessible thanks to our small intervention.” Related: Tom Dixon’s dazzling Lens pendant lamps are made from 60 lenses The most eye-catching of Dixon’s pieces are the silver-coated CURVE lights that hang like a chandelier in the church’s main space and offer a sharp contrast with the colorful stained glass windows. The designer’s easily recognizable geometric chairs and tables have been added to an upstairs co-working space , while other furnishings populate the area close to the altar. The chandelier, along with a few other furnishings, has been donated to the church as gifts. + Tom Dixon Via Dezeen Images via Tom Dixon

Comments Off on NASA’s new web apps allow Earth-bound explorers to take a trip to Mars

On the third anniversary of the Mars landing of NASA’s Curiosity rover, NASA has released two new online apps that will allow Earth-bound explorers to take a trip to the mysterious Red Planet. Mars Trek uses real data generated from 50 years of NASA exploration to create detailed visualizations, giving citizen scientists a chance to examine the planet’s surface. Experience Curiosity puts users in the driver’s seat of the one-ton rover as it ranges across a 3D Mars simulation based on actual data gathered from Curiosity and the Mars Reconnaissance Orbiter.

Comments Off on NASA video sheds light on the dark side of the moon

Ever wonder what lurks on the dark side of the moon? Now you can see it like never before. The hemisphere of the moon that always faces away from Earth was largely uncharted until 1959, when a Soviet space probe photographed it. Now NASA has provided a whole new view of the moon’s far side, via a computer-generated video that shows the phases of the moon as seen from the side facing away from Earth.
