Astronomy Picture of the Day: Comet Iwamoto and the Sombrero Galaxy
Comet Iwamoto and the Sombrero Galaxy Comet Iwamoto (C/2018 Y1), shows off a pretty, greenish coma at the upper left in this telescopic field of view. Taken on February 4 from the Mount John Observatory, University of Canterbury, the 30 minute long total exposure time shows the comet sweeping quickly across a background of stars and distant galaxies in the constellation Virgo. The long exposure and Iwamoto's rapid motion relative to the stars and galaxies results in the noticeable blurred streak tracing the the comet's bright inner coma. In fact, the streaked coma gives the comet a remarkably similar appearance to Messier 104 at lower right, popularly known as the Sombrero Galaxy. The comet, a visitor to the inner Solar System, is a mere 4 light-minutes a way though, while majestic Messier 104, a spiral galaxy posing edge-on, is 30 million light-years distant. The first binocular comet of 2019, Iwamoto will pass closest to Earth on February 12. This comet's highly elliptical orbit around the Sun stretches beyond the Kuiper belt with an estimated 1,371 year orbital period. That should bring it back to the inner Solar System in 3390 AD.

After six summers of researching, testing, and recommending window air conditioners, we've learned that quiet and affordable ACs make most people the happiest—and we think the LG LW8016ER will fit the bill in most rooms. This 8,000 Btu unit cools as efficiently and effectively as any model with an equal Btu rating, and runs at a lower volume and deeper pitch than others at this price. Little extra features like a fresh-air vent, two-axis fan blades, and a removable drain plug help set it apart, too. The LG LW8016ER is a top choice for an office or den, and some people will find it quiet enough for a bedroom, too. If our main pic
Lenovo is announcing a pair of new laptops today, the Yoga 730 and Flex 14, both of which are seeing a number of small design tweaks and receiving Intel’s 8th gen processors. While there aren’t any major changes this year, the 730 is getting one notable improvement to help it stand out: it has built-in far-field mics so that it can support Alexa. The Yoga 730 is really similar to last year’s Yoga 720 : like all Yoga laptops, it has a touchscreen and can flip around into tablet mode; it starts with a price around $900 but can go much higher if you spec it out; and while it’s a well-made laptop with an aluminum body, it isn’t quite as slim or light as what Lenovo offers in its Yoga 900 series laptops. This year, the 730 has received a few... Continue reading… via The Verge - Tech Posts "http://ift.tt/2BQTs1c"
