The Event Horizon Telescope is about to announce the first ever image of a black hole. The target is Sag A*, the supermassive black hole at the center of the Milky Way galaxy. In this video we talk about how it's possible to image a black hole, how the Event Horizon Telescope works, and how astronomers assembled data from radio telescopes around the world to produce an image. Errata: At 3:05 I refer to the right side as bright and the left side as dim. It's the other way around. 🔔 Subscribe for more: https://www.youtube.com/christianready?sub_confirmation=1 🖖 Share this video with a fellow space traveler: https://youtu.be/dQz1PZ7IhHQ 🔴 Watch my most recent upload: https://goo.gl/QbRcE2 🔴 Watch our conversation with Dr. Geoffrey Bower from the EHT project: https://youtu.be/SrTipA9WxAM 🚀 Help me improve the channel by joining the community on Patreon https://patreon.com/launchpadastro 🚀 Check out Launch Pad merchandise! https://teespring.com/stores/launchpadastro Disclaimer: Some of these links go to one of my websites and some are affiliate links where I'll earn a small commission if you make a purchase at no additional cost to you. 🐟 From out of town?

Thomas Gresham lived from 1519 to 1579. So much has happened since his time, yet many of the questions about our cosmic origins still remain. A lecture by Joseph Silk, Gresham Professor of Astronomy 6 March 2019 https://www.gresham.ac.uk/lectures-and-events/astronomy-gresham-21st-century Thomas Gresham lived from 1519 to 1579. The first telescope was designed in 1608 in the Netherlands, and first pointed at the heavens by Galileo a year later. The greatest discoveries since the pre-telescope era have been that of the existence of many other planets around distant stars, and the vastness of the universe. So much has happened since Gresham’s era, yet many of the questions about our cosmic origins still remain.

Astronomers have discovered a galaxy, called NGC 3079, is blowing bubbles in space and acting as an extraordinary particle accelerator. These "superbubbles" are likely being blown by outbursts powered by material falling onto supermassive black hole at the center of the galaxy or by winds from young stars. Stretching thousands of light years across, the superbubbles in NGC 3079 are seen in X-ray, optical, and radio emission. The particles in these superbubbles can be over a hundred times more energetic than those created by the world's most powerful accelerator, the Large Hadron Collider. Astronomers thinksuperbubbles like those in NGC 3079 may be the source of extremely energetic cosmic rays. Scientists have long been trying to track down all sources of cosmic rays, high-energy particles that regularly bombard the Earth.

Magnetic 3-lb., 2 oz. weight elegantly solves problem of out-of-balance Dobsonian tubes! For our US and Canadian customers - http://bit.ly/2EykUSs Balancing a front-heavy Dobsonian telescope can be a pain. We recently introduced an elegant solution: the Orion Magnetic 1-Pound Dobsonian Counterweight. But we realized that folks with big Dobsonians or those who are using heavier accessories on their Dobs may need more weight on the back end to achieve proper balance. So here is our newest solution: the Orion Magnetic 3-Pound Dobsonian Counterweight! Ideal for balancing Dobsonian telescopes of 10" aperture and larger, the Magnetic 3-Pound Dobsonian Counterweight works with any steel tube Dobsonian to offset heavy front-end loads, such as large eyepieces or barlow lenses, a solar filter, a big finder scope, or a smartphone mounted with an adapter for afocal photography. A counterweight is needed on the bottom end of the telescope to maintain proper balance, so that the front end won't drift downward while you're observing or photographing. Weighing 3 lbs. 2 oz., this Orion-designed counterweight consists of a ceramic block magnet encased in a steel housing with a beefy handle for easy grabbing, even with gloves on. The magnet boasts a strong 50-lb. pull strength, so it will stay put wherever you place it on the telescope's optical tube to achieve that perfect balance. Place it near the bottom of the tube for more counterbalancing effect, or closer to the altitude hubs for a more modest effect. And if one Magnetic 3-Pound Dobsonian Counterweight is not quite enough weight for optimal balance, just add a second one, or one or more 1-Pounders! The bottom surface of the Magnetic 3-Pound Dobsonian Counterweight is covered with black felt to prevent scratching of your Dobsonian telescope's finish, and includes two foam rubber stabilizing strips on the outer edges to provide a firm, non-slip grip and prevent the magnet from rocking on the curved optical tube. It has a durable black powder-coat finish. The Magnetic Dobsonian Counterweight even comes in handy balancing other types of steel-tube telescopes, such as equatorially mounted Newtonian astrographs, when more weight may be needed on the front end of the tube for proper balancing on the declination axis. Stop duct-taping that claw hammer to your Dob tube to balance that big light bucket! Get yourself a better balancing act: the Orion Magnetic 3-Pound Dobsonian Counterweight. Or two! This video provides an overview of the Orion Magnetic 3-Pound Dobsonian Counterweight. We offer several other mount and tripod accessories, many of which are described in these videos: Overview of the Orion StarShoot P1 Polar Alignment Camera https://www.youtube.com/watch?v=FdvOzrXkNLg Features of the Orion TriTech II Compact 3-Way Fluid Pan Head https://www.youtube.com/watch?v=E0TfYnDUPIw Features of the Orion StarSeek Wireless Telescope Controller https://www.youtube.com/watch?v=EhjFMiaXvIA View our complete selection of beginner telescopes: http://bit.ly/2Sp0wa4 To be notified when new videos are added to our growing library of stargazer how-to videos, subscribe to the Orion channel! http://www.youtube.com/user/oriontelescopes/ Visit https://www.telescope.com to find high quality products for amateur astronomers.

Classical Cassegrain optical design excels for high-power lunar and planetary observation and imaging. For our US and Canadian customers - http://bit.ly/2tizHdl Our CC6 6" f/12 Classical Cassegrain Telescope excels for high-resolution lunar and planetary viewing and imaging, and will get you in close on tight objects such as globular clusters and planetary nebulas. In a telescope market currently saturated with short-focal-length, wide-field instruments, the CC6 stands apart by offering something for those wanting serious magnifying capability but in a compact form factor. With an optional 10mm eyepiece you're already probing at 183x magnification. There is no pesky chromatic aberration since there are no lenses as in a refractor. The Classical Cassegrain optical design utilizes a parabolic primary mirror and a hyperbolic secondary mirror, which for the CC6 allow a long, "folded" focal length of 1836mm to be tucked into a tube just 20.5" long (including focuser). That compact tube, which weighs just 12 lbs., means the CC6 is easily supported on a modest-size mount such as the Orion Sirius EQ-G, even when equipped for photography with an extension ring and optional finder scope and imaging camera. Both mirrors are made from quartz and can take a very fine polish. The enhanced aluminum coating delivers 96% reflectivity, and a protective quartz overcoat protects the finish. The 6" primary mirror is fixed in place so you won't get image shift or mirror flop like you do from a typical Schmidt-Cassegrain or Maksutov, whose mirrors slide forward and back when focusing. With the CC6, focusing is done with a precision 2" dual-speed (10:1) Crayford focuser machined from solid aluminum. Also unlike a Schmidt-Cassegrain or Maksutov, the CC6 has no glass on the front end to dew up. It's an open tube with eight baffle rings inside to control stray light and ensure maximum contrast. Sold as an optical tube assembly only, the Orion CC6 6" Classical Cassegrain Telescope comes with TWO dovetail finder scope bases, giving you the freedom to mount an optional Orion finder scope on either side of the focuser, or to mount a small guide scope and finder scope simultaneously. A V-style dovetail mounting bar affixed to the optical tube allows its attachment to any telescope mount equipped with a compatible saddle plate. Also included are three glare-threaded extension rings: one 50mm and two 25mm in length, to allow focus to be achieved with different eyepiece and diagonal combos or imaging cameras.

12" (304mm) aperture, f/8 Ritchey-Chrétien optics housed in a thermally stable carbon fiber Serrurier-design truss tube assembly. For our US and Canadian customers - http://bit.ly/2N4gdSM The new Orion 12" f/8 Truss Tube Ritchey-Chrétien Astrograph features premium quartz mirror optics housed in an ingenious truss tube support structure originally developed back in 1935 for the 200" Hale Telescope at the Palomar Observatory! This exquisitely engineered telescope is optimized for large-aperture astrophotographic excellence - and will take your imaging pursuits to a whole new level! Unlike conventional Newtonian reflector and Schmidt-Cassegrain designs that are susceptible to displaying coma away from the center of the field, the Orion 12" f/8 Truss Tube Ritchey-Chrétien Astrograph utilizes hyperbolic primary and secondary mirrors to achieve wonderfully flat images that are virtually coma-free. Plus, since there are no lenses involved, images are delightfully free of chromatic aberration, for true-color performance. Both the 12" (304mm) primary mirror and the secondary mirror are figured from low-expansion quartz glass and boast enhanced aluminum coatings to provide 96% reflectivity. The primary mirror is fixed in place to eliminate annoying "image shift" that plagues Schmidt- and Maksutov-Cassegrain telescopes. The secondary mirror is precisely center-marked to facilitate collimation. The Serrurier carbon fiber truss system is thermally very stable, minimizing the effect of ambient temperature changes on the telescope's focus. Plus, since it's an open tube, the optics cool down faster than solid tube versions. The Serrurier system utilizes two sets of opposing truss tubes on either side of the declination pivot plane, which keep the optical elements parallel to each other no matter how the telescope is oriented, thus keeping optical collimation precisely intact. Stainless steel ball and socket hardware connects the truss tubes to the telescope's three large CNC-machined aluminum support plates. The focuser on the Orion 12" f/8 Truss Tube Ritchey-Chrétien Astrograph is a masterpiece of rigidity and precision. The CNC-machined 3.3" dual-speed (10:1) linear bearing Crayford focuser features a stainless steel rail on the drawtube that provides extra support for up to 9 lbs. of imaging gear without flexure or slippage. The focuser can be rotated 360 degrees for image framing. Both 2" and 1.25" non-marring compression ring accessory collars permit the use of 2" or 1.25" accessories.

Artist's concept illustrating Supernova 1987A as the powerful blast wave passes through its outer ring and destroys most of its dust, before the dust re-forms or grows rapidly. Observations from NASA and DLR's SOFIA reveal that dust — a building block of stars and planets — can re-form or grow immediately after the catastrophic damage caused by the blast wave.

Stuart Eves takes us on a tour of the solar system, covering the evolution of the stars and planets and describing some of the mysteries that we have yet to solve. Subscribe for regular science videos: http://bit.ly/RiSubscRibe Since the start of the space age in 1957, our understanding of the solar system has increased enormously thanks to both space-based telescopes and spacecraft that have been sent to visit the planets. Although these missions have answered many questions, they have also collected a great deal of information that fundamentally challenges our understanding of the formation and evolution of the solar system. Stuart Eves will explain the mysteries of our local neighbourhood that we have yet to unravel. Stuart Eves is a satellite-system engineer. He has recently joined Vaeros Ltd. after spending 14 years with Surrey Satellite Technology Limited (SSTL) and 16 years with the UK Ministry of Defence. During his time with the MoD, Stuart initiated the TopSat satellite programme, which established a new world record for ‘resolution per mass of satellite’, and for a time formed part of the space gallery at the Science Museum. He has recently published ‘Space Traffic Control’, a book which describes the measures needed to maintain the space environment and protect satellites from both natural hazards and man-made threats such as space debris. Stuart has an MSc in Astrophysics, a PhD in constellation design, and has been a fellow of both the Royal Astronomical Society and the British Interplanetary Society for more than 25 years. He takes an active interest in all things space, and is thus best described as an ‘astro-nut’!

What can you see in the February sky? Stars and planets with distinct red and blue colors, like Mars and Sirius. February also brings some pretty pairings with Venus, Saturn and the Moon, and the best opportunity of the year to catch a glimpse of Mercury. We also point out locations in the sky of several destinations recently visited by NASA spacecraft.

Scientists think that within 10 million years of our solar system’s formation, Bennu’s present-day composition was already established. Bennu likely broke off from a much larger carbon-rich asteroid about 700 million to 2 billion years ago. It likely formed in the Main Asteroid Belt between Mars and Jupiter, and has drifted much closer to Earth since then. Because its materials are so old, Bennu may contain organic molecules similar to those that could have been involved with the start of life on Earth.

Another episode of Night Sky News for this month - the first half what you can see in the sky this next month and the second half a recap of the space news of the last month. A lot has happened in the past month, including New Horizon’s fly by of Ultima Thule in the Kuiper Belt, China’s Chang’e4 probe landing on the Moon and growing a plant (!), results from the Cassini mission which have let us figure out how old Saturn’s rings are and more detections of these unexplained fast radio bursts. I already made a video about Fast Radio Bursts in my Unsolved Mysteries series, check it out here: https://www.youtube.com/watch?v=OLOFpGrnJ9o The audio in this video isn’t perfect - I had some issues with a high pitched whine that varied in frequency across the recording. Did my best to remove it as much as I could but it’s still there in some places where that wasn’t enough white space to get a noise profile. I clearly need a more expensive mic.

We'll be talking with Dr. Pat McCarthy and Ms. Barbara Fischer from the Giant Magellan Telescope (GMT) to learn more about its construction and capabilities. GMT is under construction in Chile and when completed will be the world's largest optical and infrared astronomical observatory (at least until the Extremely Large Telescope is completed 🙂 ). GMT uses seven 8-meter mirrors to produce 🔔 Subscribe for more: https://www.youtube.com/christianready?sub_confirmation=1 🖖 Share this video with a fellow space traveler: https://youtu.be/p7CZqhnyLqo This video is a collaboration with Tony Darnell at Deep Astronomy.

Telescope Talk Hangouts are sponsored by OPT Telescopes: https://bit.ly/2SwhmVB The Giant Magellan Telescope will be one member of the next class of giant ground-based telescopes that promises to revolutionize our view and understanding of the universe. It will be constructed in the Las Campanas Observatory in Chile. Commissioning of the telescope is scheduled to begin in 2024. The GMT has a unique design that offers several advantages. It is a segmented mirror telescope that employs seven of today’s largest stiff monolith mirrors as segments. Six off-axis 8.4 meter or 27-foot segments surround a central on-axis segment, forming a single optical surface 24.5 meters, or 80 feet, in diameter with a total collecting area of 368 square meters. The GMT will have a resolving power 10 times greater than the Hubble Space Telescope. The GMT project is the work of a distinguished international consortium of leading universities and science institutions.
