Eventually, everyone wants to take pictures of the night sky with their telescopes. It's not exactly a beginner activity, but it is one of the most rewarding feelings when you've processed an image you took yourself. We also live in an age when you can processing images directly from spacecraft orbiting other worlds in our solar system. There is also a multitude of citizen science projects that we can all get involved with. Please join Tony Darnell, Adam Synergy Smith, John Suffill and Alexander Reinders as we discuss some of the amazing possibilities open to amateurs with our guest Jason Major, one of the foremost science communicators and imaging enthusiast.

Eta Carinae, is a well known massive, luminous star system located about 7,500 light-years away from the Earth. It is in the southern constellation of Carina, and produced an outburst in the 19th century making it the second-brightest star in the sky. Since then, Eta Car has been well studied but still it holds fascination for astronomers studying explosive star systems. It has two massive stars that come very close to each other every 5.5 years. The system has intense outflows which accelerate charged particles to an amazing speed and can produce energy bursts that can be observed by many telescopes. Studies with the NuSTAR space telescope recently have helped characterize the outbursts and the types of particles sent our way Join Tony Darnell and Carol Christian during Afternoon Astronomy Coffee on July 12 at 3PM Eastern time as they discuss with the investigators, including Kenji Hamaguchi of Goddard Space Flight Center (GSFC) and U. of Maryland (UMBC) and Michael Corcoran of GSFC and Catholic University how they probed Eta Car with NuSTAR to understand the system, and they will describe this interesting NASA mission that probes the high energy universe.

Naturalist and author Bernie Taylor presents an origin to modern astronomy in European Paleolithic caves from 34,000 years ago that connects with global myths of hunter-gatherers and the ancients in the Mediterranean region. Taylor proposes that astronomy was developed to pass on timeless myths and cultural traditions among prehistoric hunter-gathers. He will explore deep sources to Ptolemy's Almagest and the hero's journey monomyth of Joseph Campbell as popularized in the Star Wars movie series, and test the precession of the equinoxes against the Paleolithic record.

Evidence for dark matter has been known for some time, and it is expected that it interacts with the familiar luminous matter that we see in the universe in some normal way. Yet, although dark matter seems to account for the fact that galaxies are able to hold together with gravity, it does not behave as normal matter in other respects. It seems to be evident in gravitational lenses, yet we cannot observe it directly. Otherwise dark matter seems to only weakly interact with ordinary matter. A recent scientific study of radio data was interpreted to be evidence for the formation of stars, and further, a signal of interaction between normal and dark matter. The physics of the situation appears tricky though, and a team of scientists has proposed that maybe dark matter actually has a tiny bit of electric charge. This would be remarkable and has some interesting consequences. Join Tony Darnell and Carol Christian during Afternoon Astronomy Coffee on June 14 at 3PM Eastern time as they discuss with the investigators, Avi Loeb, Cora Dvorkin, and Julian Munoz (Harvard University) this amazing idea and the implications their model has for understanding dark matter and the make up of the universe.

Please consider becoming a patron: https://patreon.com/DeepAstronomy Astronomers were enthusiastic but cautious about the Hubble observations that suggested Europa had water plumes ejected from its icy surface. Every telescope observation of these eruptions was at the limit of detection. Then, it was suggested that that a thermal signature had been recorded by the Galileo satellite years before, right at the corresponding position on Europa's surface. Now, digging through the archives of Galileo, a team has carefully re-analyzed the data and discovered that the satellite may actually have flown through a plume. Europa's icy surface likely is a crust over a global ocean. Through cracks in that surface, water can spew out in a huge plume. As a result of a re-analysis of Galileo's measurements combined with a model including constraints of the plumes observed by Hubble, it appears as though Galileo flew through a similar plume in 1997. Thus it seems there is strong independent evidence of the presence of plumes at Europa. Join Tony Darnell and Carol Christian during Afternoon Astronomy Coffee on May 24 at 3PM Eastern time as they discuss with the investigators, Xianzhe Jia (U Michigan), Margaret Kivelson and Krishan Khurana (UCLA), and William Kurth (U Iowa) how they combed the Galileo archive and what their analysis yielded.

Surprisingly, it may be easier to get to Mars orbit one day with astronauts than it will be to actually land: safely landing on the Red Planet poses some major challenges yet to be overcome. So far, many Mars landers and rovers have used a variety of technologies to keep from crashing onto the Martian surface, everything from protective inflatable bags to retro-firing rocket and parachutes. It is far from clear however, what technology and methods will be used to safely land humans. Please join our Hangout, when our regular moderator, Tony Darnell, will discuss the present and future of landing on Mars with Tara Polsgrove (NASA Marshall Space Flight Center) and Michelle Munk (NASA Langley Research Center).

Astronomers believe there is an undiscovered super-Earth Sized planet lurking in our outer solar system. If it exists, then astronomers think it would have an estimated mass of ten Earths, a diameter two to four times that of Earth, and an elongated orbit lasting approximately 15,000 years. So far, efforts to find this planet have failed. They are calling it Planet Nine and astronomers are seriously trying to find it. Our guests today have written a paper outlining efforts to locate this planet using WISE and NEOWISE data. They think that Planet Nine, if it exists, should be self-luminous enough and potentially bright enough in the near infrared that the NEOWISE telescope should be able to see it. Today we’ll talk about those efforts along with what WISE and NEOWISE is, why we think Planet Nine is there in the first place, and whether or not it will have any adverse effect on the Earth anytime soon. Scientists are searching for this illusive body in our solar system using all the data they can find and obtain with observatories including those in space. It is speculated that this planet orbits the Sun very far out in the solar system, at hundreds of times the distance from the Earth to the Sun (one Astronomical Unit). It could be that the planet shines on its own in the infrared, making it perfect for the Wide Field Infrared Explorer (WISE) satellite. A clever methodology by scientists is aimed to detect very faint moving objects. What is the result? Join Tony Darnell and Carol Christian during Afternoon Astronomy Coffee on May 10 at 3PM Eastern time as they discuss with Aaron Meisner (UC Berkeley), Ben Bromley (U of Utah), and Scott Kenyon (Smithsonian Astrophysical Observatory) their deep search for Planet Nine and what they found.

Having discovered the "Hot Jupiter" type of planets, researchers now looking for smaller and colder objects. Taking a lesson from our own solar system, it does appear that things that might qualify as planets elsewhere might be moons in our own system. Take for example Saturn's moon Titan, and also Jupiter's moon Ganymede. These objects may harbor water and conditions conducive to life. What if we found such objects around other stars?

The discovery of this dim object heralds in a new class of galaxies that have become known as ‘dark galaxies’ or ‘ultra diffuse galaxies’ because they contain relatively few stars, yet have a mass equal to our own Milky Way with hundreds of billions of stars. It was only discovered recently, in 2015, when the Dragonfly Telephoto Array, then a small collection of 24 commercially available 400mm telephoto lenses, looked towards a region of sky in the constellation Coma. But as astronomers looked closer using larger telescopes with specialized instruments, they realized this dim, tiny galaxy was more than meets the eye - literally. It contained so few stars. There were so few stars in this galaxy that there was no way they could all stay together as a gravitationally bound object - they would simply fly apart. So what was keeping the stars in Dragonfly 44 together? Astronomers had pretty good idea: dark matter. Dragonfly 44 image Pieter van Dokkum / Roberto Abraham / Gemini Observatory / SDSS / AURA.

We live in a time when searching for and finding the faintest galaxies in the universe is possible. So, where are they? The universe contains galaxies at many scales, from diffuse objects to the massive galaxies containing supermassive black holes, often contained in large clusters of galaxies of diverse types. It is interesting to understand how faint galaxies get - do they include even what might be called a mere "collections of stars", larger than star clusters, but not containing organized shapes like spiral galaxies do? How are such illusive objects found? Do computational models predict that such objects exist, and what do they contain? In the nearby universe surveys are used to discover them, but those can only uncover a limited sample of such objects. Join Tony Darnell and Carol Christian during Afternoon Astronomy Coffee on March 8, 2018 at 3PM Eastern Time as they discuss with Shany Danieli, Pieter van Dokkum and Dr. Marla Geha (Yale University) the prospects for finding these “integrated light” images of dwarfs, and what telescopes would be optimum for conducting the searches.

I had this idea for a contest as I was trying to add images to the Worldwide Telescope Client. I need your help! Here are the details of the contest. I want to add this image to Worldwide Telescope: http://astropix.ipac.caltech.edu/image/esahubble/heic1307a That is an amazing image of the Horsehead Nebula taken to celebrate the 23rd anniversary of the Hubble Space Telescope. What's great about it is the level of detail one can see in the infrared wavelengths of the Wide Field Camera 3 on Hubble. The problem is, I can't just copy and paste the image into Worldwide Telescope. In order to know where to place the image in the sky and scale it properly, WWT needs more information, namely the World Coordinate System (WCS) information. Usually, that information is in the headers of the science data in FITS format, but these images are jpegs and png's, not FITS. To give jpg images processed for science outreach, NASA and others have developed a header for these images called the Astronomy Visualization Metadata (AVM) which is essentially a FITS header for jpgs and pngs. More about AVM here: http://astropix.ipac.caltech.edu/page/4 So the trick is to get the WCS data from the FITS images into the AVM header for the Horsehead jpg and then WWT will know what to do with it. To get the FITS images, we can go to the MAST Archive where all Hubble data are kept and get the Horsehead files: http://archive.stsci.edu/hst/search.php And search using Target Name=Horsehead and Prop ID=12812 That will return 14 or so FITS images. Download them all and get the WCS info from them and put them in the AVM header in the Horsehead jpgs. So, the challenge: create an AVM header that will import into the WWT for the Horsehead image linked to above. Here are some links that might help. Link to a howto from STScI: http://www.stsci.edu/~harrisj/HTML/howto3.html Some AVM resources: http://avm.ipac.caltech.edu/about The PRIZE: First up, you'll get my undying respect and a request to make some more for WWT. You'll also be contributing to a great resource for astronomy outreach.

The outskirts of our solar system is a region dominated by the solar wind flowing away from the Sun and encountering the interstellar material (ISM) in space. The solar wind is also magnetized and creates a bubble, called the heliosphere, around our planetary system. The bubble's shape depends on the strength of the wind and the properties of the ISM. But this distant region is difficult to probe. In order to understand what is going on in the heliosphere, data from the Voyager space craft and the International Boundary Explorer (called IBEX) have been used. IBEX is able to measure atoms in the heliosphere and the Voyager spacecraft measure the properties of the plasma field. Importantly though, all this accumulated information must be fed into complicated models to understand the detailed structure of the boundary layer. Join Tony Darnell and Carol Christian during Afternoon Astronomy Coffee on February 22, 2018 at 3PM Eastern (Daylight) Time as they discuss with Nikolai Pogorelov (University of Alabama), and Jacob Heerikhuisen (University of Alabama) about unraveling the data collected and the success in modeling the heliosphere boundary.

Why go through all the trouble and expense of buying and learning to use your own imaging equipment when you have access to ACTUAL Space Telescope data? If you've ever wanted to take a picture like the Hubble Space Telescope does of the Orion Nebula or capture Jupiter through the camera as well as the Juno spacecraft, then this hangout is for you. You can actually use data from these missions yourself. The data taken with all space telescopes eventually end up in the public archives that you can download and process yourself. In this hangout we'll discuss some of the ways of getting and processing this data for your own use. We'll also take some time to talk about what its like to have job processing data from these major missions and some of the requirements of that job.

The Transiting Exoplanet Survey Satellite (TESS) is scheduled to launch later this year. Where does the mission stand? Join us for the first Future in Space Hangout for 2018 as we take a look at the status of the TESS mission and discuss some of the amazing science it is designed to accomplish. As always, we hope you'll join in on the discussion via our Discord server: https://discord.gg/nqGpvtK

Over the three years of the K2 mission, 287,309 stars have been observed, and tens of thousands more roll in every few months. So how do astronomers sift through all that data? A new discovery of a planetary system around the star K2-138 containing five planets that contain ice and gas, and maybe even be rocky is a result of observations with the K2 (Kepler extension) mission. Data from the K2 mission is made available to everyone through Zooniverse, a citizen science portal. A software package containing a signal-detection algorithm identifies potential transit signals in the K2 data. Those targets are made available to the public to peruse and find interesting objects. The website contains a training module so that interested individuals can quickly learn what to search for. The new, tightly packed planetary system contains planets between the size of Earth and Neptune that are circular, compared to our own solar system where the planets have elliptical orbits. The orbits of the planets are short - between 2 and 13 days! This means they are close to their parent K-type star and therefore are quite hot. Join Tony Darnell and Carol Christian during Afternoon Astronomy Coffee on February 8, 2018 at 3PM Eastern (Daylight) Time as they discuss with Jessie Christiansen (CalTech) and collaborators about the new planetary system and the citizen science effort.
