Big Picture, Big Data: Swiss Unveil VR Software of Universe

3 months ago 88

LAUSANNE, Switzerland—The last frontier has seldom seemed person than this—at slightest virtually.

Researchers astatine 1 of Switzerland’s apical universities are releasing open-source beta bundle connected Tuesday that allows for virtual visits done the cosmos including up to the International Space Station, past the Moon, Saturn oregon exoplanets, implicit galaxies, and good beyond.

The program—called Virtual Reality Universe Project (VIRUP)—pulls unneurotic what the researchers telephone the largest information acceptable of the beingness to make three-dimensional, panoramic visualizations of space.

Software engineers, astrophysicists, and experimental museology experts astatine the Ecole Polytechnique Federale de Lausanne (EPFL) person travel unneurotic to concoct the virtual representation that tin beryllium viewed done idiosyncratic VR gear, immersion systems similar panoramic cinema with 3D glasses, planetarium-like dome screens, oregon conscionable connected a PC for two-dimensional viewing.

“The novelty of this task was putting each the information acceptable disposable into 1 framework, erstwhile you tin spot the beingness astatine antithetic scales—nearby us, astir the Earth, astir the star system, astatine the Milky Way level, to spot done the universe,” said Jean-Paul Kneib, manager of EPFL’s astrophysics lab.

Think a benignant of Google Earth, but for the universe. Computer algorithms churn up tens of terabytes of information and nutrient images that tin look arsenic adjacent arsenic 1 metre (about 3 feet), oregon astir infinitely acold away—as if you beryllium backmost and look astatine the full observable universe.

VIRUP is accessible to everyone for free—though it does necessitate astatine slightest a machine and is champion visualized with VR instrumentality oregon 3D capabilities. It aims to gully successful a wide array of visitors, some scientists looking to visualize the information they proceed to cod and a wide nationalist seeking to research the heavens virtually.

Still a enactment successful progress, for now, the beta mentation can’t beryllium tally connected a Mac computer. Downloading the bundle and contented mightiness look onerous for the least-skilled machine users, and space—on a computer—will count. The broader-public mentation of the contented is simply a reduced-size mentation that tin beryllium quantified successful gigabytes, a benignant of best-of highlights. Astronomy buffs with much disk abstraction mightiness take to download more.

The task assembles accusation from 8 databases that number astatine slightest 4,500 known exoplanets, tens of millions of galaxies, hundreds of millions of abstraction objects successful all, and much than 1.5 cardinal airy sources from the Milky Way alone. But erstwhile it comes to imaginable data, the entity is virtually the limit: Future databases could see asteroids successful our star strategy oregon objects similar nebulae and pulsars farther into the galaxy.

To beryllium sure, VR games and representations already exist: Cosmos-gazing apps connected tablets let for mapping of the nighttime sky, with zoom-in close-ups of heavenly bodies; bundle similar SpaceEngine from Russia offers beingness visuals; NASA has done immoderate smaller VR scopes of space.

But the EPFL squad says VIRUP goes overmuch farther and wider: Data pulled from sources similar the Sloan Digital Sky Survey successful the United States, and European Space Agency’s Gaia ngo to representation the Milky Way and its Planck ngo to observe the archetypal airy of the universe, each brought unneurotic successful a one-stop-shop for the astir extended information sets yet around.

And there’s much to come: erstwhile the 14-country scope task known arsenic the Square Kilometer Array starts pulling down information, the information could beryllium counted successful the petabytes—that’s 1,000 terabytes oregon 1 cardinal gigabytes.

Strap connected the VR goggles, and it’s a unusual feeling seeing the Moon—seemingly the size of a elephantine formation shot and floating adjacent capable to hold—as the skyline rotates from the sunny broadside to the acheronian broadside of the lunar surface.

Then velocity retired to beyond the star strategy and plaything by Saturn, past up supra the Milky Way, swirling and flashing and heaving—with exoplanets highlighted successful red. And overmuch farther retired still, ideate floating done tiny dots of airy that correspond galaxies arsenic if the spectator is an unconscionably ample elephantine floating successful space.

“That is simply a precise businesslike mode of visiting each the antithetic scales that constitute our universe, and that is wholly unique,” says Yves Revaz, an EPFL astrophysicist. “A precise important portion of this task is that it’s a archetypal measurement toward treating overmuch larger information sets which are coming.”

Entire galaxies look to beryllium strung unneurotic by strands oregon filaments of light, astir similar practice of neural connections, that nexus up clusters of airy similar galaxies.

“We really started this task due to the fact that I was moving connected a three-dimensional mapping task of the beingness and was ever a small frustrated with the 2D visualization connected my screen, which wasn’t precise meaningful,” said Kneib, successful a country successful a nondescript laboratory gathering that houses a panoramic screen, a half-dome cinema with bean-bag seating, and a hard-floor abstraction for virtual-reality excursions.

“It’s existent that by showing the beingness successful 3D, by showing these filaments, by showing these clusters of galaxies which are ample concentrations of matter, you truly recognize what the beingness is,” helium added.
