NASA farewell view of Ultima Thule shows a giant pancake

We’ve never seen something like this orbiting the Sun,” said principal investigator Alan Stern.NASA also offered up a short departure movie showing New Horizons’ view as it zipped by. The movie is compiled from 14 different images of Ultima Thule.

NASA/Johns Hopkins Applied Physics Laboratory/Southwest Research Institute/National Optical Astronomy Observatory NASA must be hungry. The space agency shared the New Horizons spacecraft’s goodbye glance at weird Ultima Thule and decided it looked like a “giant pancake” attached to a “dented walnut.”Ultima Thule is an unusual object found in the Kuiper Belt. It’s located about 1 billion miles past dwarf-planet Pluto, which New Horizons visited in 2015. The pancake and nut comparison is a departure from earlier images that showed the two-lobed object looking more like a snowman.NASA released a graphic showing how our understanding has changed thanks to additional data from New Horizons. nasaultimaEnlarge ImageThis illustration shows NASA’s old and new views of Ultima Thule. NASA/Johns Hopkins Applied Physics Laboratory/Southwest Research Institute The rounded snowman images came within a day of New Horizons’ closest approach on Jan. 1. Images taken 10 minutes after the approach highlighted a view of the object’s crescent, giving scientists a better idea of its actual shape. The blue dashes in the illustration show NASA’s fudge factor. Ultime Thule may fill out those lines, or it may be closer to the flatter shape shown.  Post a commentcenter_img NASA contemplates Ultima Thule 0 New Horizons launched in 2006 and has since traveled billions of miles through space, with notable visits to Pluto and now Ultima Thule. The spacecraft is healthy and its handlers may look into sending it toward another interesting target. We’ll just have to wait and see what it finds out there so far from home.

Cutting Edges

first_imgBy Imani Wj Wright, Baltimore Resident“The Barbershop Series” exhibition features the work of renowned Baltimore artist, puppeteer and museum educator Schroeder Cherry, Ed.D. The series pays homage to one of the most enduring African American economic and cultural institutions, using bold colors, movement, symbols and visual metaphors. Each piece is a multimedia collage emulating the voices, sounds, textures and personas that make barbershops a central place in communities around the nation.This past weekend, I had the opportunity to analyze and spectate “The Barbershop Series,” a collaboration between visual artist, Schroeder Cherry and Joshua Lee, a mental health therapist. The series opened with a curated event by L. Nef’fahtiti Partlow-Myrick. Cherry began these conversations in 2015 and continues the narrative of open communication in inner city communities. Conversations that account for real Black voices in the communities that people listen to least.Growing-up, my father and I would get our hair cut every other Friday at Session’s Barbershop. There were days where my father and I would wait until 1 a.m. to finally get our cut and end up leaving at about 2 a.m. Even though I was young, I was never impatient. Time seemed to fly by so fast. There was always such good conversation throughout the shop. Not just [small talk], but intense, passionate and socially dogged discussions. At Session’s, the topics would vary, and often did.  Anything you could name- from history, to sports, to the three branches of government, there was a little bit of everything. I quickly realized that barbershops were a massive nucleus for dialogue.“The Barbershop Series,” blended the work of renowned Baltimore artist Schroeder Cherry, Ed.D and the mental health therapy of Joshua Lee, to curate an art therapy experience where attendees “unlocked,” key things about the world and their lives. (Photos by Niya Parham)Videographer, Lukey Lenz and I were allowed access to the art gallery.  We spent two-hours trying to take everything in and figure out exactly what the messages were in these pieces of art. One motif that we came across were locks. There were physical locks attached to the pieces. And along with these locks, fittingly so, there were sets of keys.After some “ice breaking”, it was time for Lee to get everyone started with the crux of the “event.” He said to everyone, “If you were a lock, show me what that would look like. Show me a soft lock, Show me a hard lock.” We even got a little unconventional with pretty locks. At first, people hesitated, but swiftly found a way to show their bodily interpretations of what each lock looked and felt like to them. Afterwards, participants were sectioned off into groups to discuss the topic in which was assigned to them. Two of the presented topics were lock and unlock.“The Barbershop Series,” blended the work of renowned Baltimore artist Schroeder Cherry, Ed.D and the mental health therapy of Joshua Lee, to curate an art therapy experience where attendees “unlocked,” key things about the world and their lives. (Photos by Niya Parham)Michelle Holder, a woman who was discussing “unlock,” made a very memorable statement. Holder said, “When I heard lock, I closed my eyes. I didn’t want anything to do with my surroundings.”  Another man, proudly sporting a dashiki, said, “I thought of the chains on my people from wrist to ankle.” A few steps over to the left there was a group of folk speaking on lock. The atmosphere was the same in this circle.. serious, and introspective. A young woman named Nicole explained: “I don’t know what the end goal is of the key. I don’t know.  I don’t know the key to anger.” Words and phrases like, “uncomfortable,” “exposed,” and “I cut myself from the world,” were all consistently heard throughout the room. At points, some even began to break out in tears. This was deeper than an exercise, this was deeper than great art, this was people finding pieces of their spirit that they may have never unlocked. Cherry’s art simply became what art is typically used for, and becomes in the real world…. inspiration. The participants weren’t just looking at the assemblage  art on the wall and analyzing the pieces for what they were. The art had now been given legs. It lead to a community event, a thinking tank, a moment of self reflection.Schroeder Cherry, Joshua Lee, and everyone else involved with the curation of the Barbershop Series deserves a grand applause. I, along with many others in that room, experienced what art and humanity can truly accomplish in tandem. I hope future artists can use this model to expand their piece…surpassing the canvas. In the meantime.. Stay Virtuous. Stay Idealistic. Stay Progressive. “The AFRO is committed to providing an experience like no other. In a new segment entitled “Baltimore Speaks,” the AFRO gives its readers a chance to write about their experiences in neighborhoods around Baltimore.”last_img read more

Luxims tiny plasma lightbulb outshines LEDs

first_img Explore further A Tic-Tac-sized lightbulb that gives off as much light as a streetlamp may offer a peek at the ultra-efficient lighting of the future. The bulb, developed by Luxim of Sunnyvale, California, uses plasma technology to achieve its brightness. Citation: Luxim’s tiny plasma lightbulb outshines LEDs (2008, March 20) retrieved 18 August 2019 from New nanomaterial to replace mercurycenter_img This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. The tiny bulb contains an argon gas in the middle, as well as a component called a “puck.” The bulb is partially embedded in a dielectric material. When electrical energy is delivered to the puck, the puck acts like an electrical lens. It heats up the argon to a temperature of 6000 degrees Kelvin, and turns the gas into a plasma that gives off light. The plasma, whose 6000-degree temperature is similar to that of the surface of the sun, also emits a spectrum that looks very similar to the spectrum of sunlight.The plasma bulb uses 250 watts, and achieves around 140 lumens per watt, making it very bright and highly efficient. By comparison, conventional lightbulbs and high-end LEDs get around 15 and 70 lumens per watt, respectively. “A key advantage is that the energy is driven into the bulb without any electrodes, so you don’t need any electrical connections to get the energy into the bulb,” Luxim CEO Tony McGettigan explained to ZDNet. Luxim is using different versions of its electrode-less plasma technology to develop lighting for ultra-bright projection displays, retail and street lighting, microscope lighting, and various medical applications.More information: via: ZDNetlast_img read more
