Hubble Telescope Image Shows Two Galaxies Colliding 350 Million Light-Years Away

Since launching in 1990, the Hubble Space Telescope has captured some magnificent images of our corner of the universe, from neighboring planets to distant nebulae. An updated picture released by the European Space Agency shows two galaxies colliding 350 million light-years away, a process the ESA has been tracking for 52 years, Gizmodo reports.

Galaxies are constantly changing shape and creeping through space. When two of these massive networks cross paths, their stellar material begins to intermingle, and they eventually merge into one entity under the force of gravity. In this image depicting two barred spiral galaxies in the Cetus constellation, the two nuclei are still separate, but the explosive merging process has already been set in motion. Long tidal tails—streams of gas, dust, and stars—feather out from the top of the cluster. The bright blue patches indicate "stellar nurseries" where gas and dust stirred together by gravity are producing new stars.

The photograph was first released in 2008, but this latest version has been updated using Hubble's Advanced Camera for Surveys (ACS) and the Wide Field Camera 3 (WFC3). According to an ESA statement, the galaxies "are like a natural experiment played out on a cosmic scale, and by cataloguing them, astronomers can better understand the physical processes that warp spiral and elliptical galaxies into new shapes."

Galactic mergers are a vital part of the evolution of the universe: Even the Milky Way is on course to crash into a neighboring galaxy 4 billion years down the road. But the process, though violent, is slow-moving. It will be millions of years before these two galaxies in Cetus settle down into one.

Stephen Hawking’s Memorial Will Beam His Words Toward the Nearest Black Hole

An upcoming memorial for Stephen Hawking is going to be out of this world. The late physicist’s words, set to music, will be broadcast by satellite toward the nearest black hole during a June 15 service in the UK, the BBC reports.

During his lifetime, Hawking signed up to travel to space on Richard Branson’s Virgin Galactic spaceship, but he died before he ever got the chance. (He passed away in March.) Hawking’s daughter Lucy told the BBC that the memorial's musical tribute is a “beautiful and symbolic gesture that creates a link between our father's presence on this planet, his wish to go into space, and his explorations of the universe in his mind.” She described it as "a message of peace and hope, about unity and the need for us to live together in harmony on this planet."

Titled “The Stephen Hawking Tribute,” the music was written by Greek composer Vangelis, who created the scores for Blade Runner and Chariots of Fire. It will play while Hawking’s ashes are interred at Westminster Abbey, near where Isaac Newton and Charles Darwin are buried, according to Cambridge News. After the service, the piece will be beamed into space from the European Space Agency’s Cebreros Station in Spain. The target is a black hole called 1A 0620-00, “which lives in a binary system with a fairly ordinary orange dwarf star,” according to Lucy Hawking.

Hawking wasn't the first person to predict the existence of black holes (Albert Einstein's general theory of relativity accounted for them back in the early 1900s), but he spoke at length about them throughout his career and devised mathematical theorems that gave credence to their existence in the universe.

Actor Benedict Cumberbatch, a friend of the Hawking family who portrayed the late scientist in the BBC film Hawking, will speak at the service. In addition to Hawking's close friends and family, British astronaut Tim Peake and several local students with disabilities have also been invited to attend.

IKEA's New Collection for Tiny Apartments Is Inspired by Life on Mars

Living in a city apartment can feel claustrophobic at times. As Co.Design reports, the Swedish furniture brand IKEA took this experience to the extreme when designers visited a simulated Mars habitat as research for their latest line of housewares aimed at urbanites.

The new collection, called Rumtid, is tailored to fit the cramped spaces that many people are forced to settle for when apartment-hunting in dense, expensive cities. The designers knew they wanted to prioritize efficiency and functionality with their new project, and Mars research provided the perfect inspiration.

At the Mars Society's Mars Desert Research Station in Utah, scientists are figuring out how to meet the needs of potential Mars astronauts with very limited resources. Materials have to be light, so that they require as little rocket fuel as possible to ferry them to the red planet, and should ideally run on renewable energy.

IKEA's designers aren't facing quite as many challenges, but spending a few days at the simulated Martian habitat in Utah got them thinking on the right track. The team also conducted additional research at the famously snug capsule hotels in Tokyo. The Rumtid products they came up with include an indoor terrarium shaped like a space-age rocket, a set of colorful, compact air purifiers, and light-weight joints and bars that can be snapped into modular furniture.

The collection isn't ready to hit IKEA shelves just yet—the chain plans to make Rumtid available for customers by 2020. In the meantime, the designers hope to experiment with additional science fiction-worthy ideas, including curtains that clean the air around them.
