Hubble captures stunning gravitational interaction between a trio of galaxies

05 Aug

NASA has published a stunning image captured by the Hubble Space Telescope that shows a ‘three-way gravitational tug-of-war between interacting galaxies.’ The galaxies in the show are in system Arp 195, a system featured in the Atlas of Peculiar Galaxies, a list of the ‘weirder and more wonderful galaxies in the universe.’

Arp 195, otherwise known as UGC 4653, is a galaxy with material ejected from nuclei. It’s one of 15 Arp-numbered galaxies with this characteristic. All but one of these galaxies are interacting or have recently interacted with other celestial objects. The trademark tidal features of the galaxies, including Arp 195, appear to be the result of gravitational interactions.

Hubble’s new sighting is in the Lynx constellation, about 747 million light-years from Earth. It’s fantastic to see new images from Hubble, as the venerable space telescope suffered significant downtime following a computer glitch earlier this summer. Hubble recently returned to service and celebrated by publishing a pair of stunning monochromatic images last month.

‘These images, from a program led by Julianne Dalcanton of the University of Washington in Seattle, demonstrate Hubble’s return to full science operations. [Left] ARP-MADORE2115-273 is a rarely observed example of a pair of interacting galaxies in the southern hemisphere. [Right] ARP-MADORE0002-503 is a large spiral galaxy with unusual, extended spiral arms. While most disk galaxies have an even number of spiral arms, this one has three.’ Text and image credit: Science: NASA, ESA, STScI, Julianne Dalcanton (UW) Image processing: Alyssa Pagan (STScI).

The hiatus aside, Hubble’s observational time is valuable. NASA writes, ‘Observing time with Hubble is extremely valuable, so astronomers don’t want to waste a second. The schedule for Hubble observations is calculated using a computer algorithm which allows the spacecraft to occasionally gather bonus snapshots of data between longer observations. This image of the clashing triplet of galaxies in Arp 195 is one such snapshot. Extra observations such as these do more than provide spectacular images – they also help to identify promising targets to follow up with using telescopes such as the upcoming NASA/ESA/CSA James Webb Space Telescope.’

Hubble offers a unique look into distant space, and it’s great to see that the telescope is working well following its concerning issue. If you’d like to see more of what Hubble is up to, you can check out an image gallery here.

Art of Interaction: 300 Reasons to Attend INSTINT 2015 in MN

21 Jul

[ By WebUrbanist in Art & Installation & Sound. ]

Featuring a combination of workshops, lectures, mixers and parties, INSTINT (from the makers of eyeo) brings together some of the most influential and exciting creatives dealing with interactive architecture, art, design and technology from around the world. With less than 60 tickets left, you would be wise to register as soon as possible and if you will be coming to Minneapolis from out of state (or country), be sure to start making travel plans today.

Attending the event last year, WebUrbanist’s founder and lead technologist were stunned by the high caliber not only of the presenters but the 300 attendees as well, all of whom had stories to share about their work in and beyond the realm of interaction design.

This year, WU is once again a proud official media partner of this amazing gathering. In addition to selected talks from last year (embedded above), more videos from INSTINT 2014 can be found on Vimeo – but keep in mind: at least half of the experience is simply interacting with others in attendance during and beyond the event, so the talks themselves tell only part of the story.

Frequently found at the bleeding edge of their intersecting fields, INSTINT’s various compelling presenters manage to show off a combination of stunning completed works while also sharing behind-the-scenes lessons for others looking to create responsive environments, interactive art or smart objects. Attendees will be inspired by the finished projects but also learn a great deal from the trials, errors and iterations described in honest detail as well.

Over three days and in addition to multiple workshops, lunches and mixers, this year’s 14 outstanding speakers include Rachel Wingfield from London, whose experiments with future scenarios combine biology with technology to create living architecture, as well as Nataly Gattengo of San Francisco’s Future Cities Lab who has won awards for robotics, responsive building systems and other developments around the Internet of Things.

More from the organizers: “Great ideas and technology create ever-new opportunities to bring projects to life everywhere and anywhere imaginable. Along with this opportunity comes the inevitable trials and challenges of physical and site specific work. One-off projects made for one-off locations can make you pull your hair out, and/or go broke in the process. The volume of variables, old and new, can be overwhelming: unpredictable environments, bleeding edge technology, custom fabrication, code, bugs, insects, greasy fingers, hackers, crashers, crashes, caches, spoilers, laws, landlords, curators, committees, workers, shippers, solder, electricity, sunlight, moonlight, fluorescent light, reflections, bad ideas, egos, feasibility, durability, production planning, scope, scale, budgets, and on, and on. What knowledge can be applied from previous experiences and what has to be learned on-the-fly, on a per project basis? INSTINT aims to arm you with insights and inspiration, and expand your ability to execute projects in this exciting, but complex, sometimes harrowing, and ever-shifting field.” Register today!
