Ion thrusters and science fiction? Nope, advanced propulsion technologies are under real development. 
For its crazy 2020 asteroid capture mission and other projects, NASA is developing next-gen "Hall effect thrusters" to corral an asteroid and put it into

#Astronomy: #N44C #Nebula: This image from NASA’s Hubble Space Telescope has captured softly glowing filaments streaming from hot young stars in a nearby nebula. The image, presented by the Hubble Heritage Project, was taken in 1996 by Hubble’s Wide Field and Planetary Camera 2, designed and built by NASA’s Jet Propulsion Laboratory, Pasadena, Calif.

If you don't have access to a telescope (or you're on the wrong side of the Earth for the upcoming lunar eclipse) why not borrow a 'scope from the Internet....

"A very powerful set of real,  robotic telescopes, remotely accessible online, through the Internet for your very own astronomical experience!"

A Gold Mine of Galaxy Nuggets: One telescope finds the treasure chest, and the other narrows in on the gold coins. Data from two European Space Telescope missions, Planck and Herschel, have together identified some of the oldest and rarest clusters of galaxies in the distant cosmos. We played a big role in both missions. Details: http://go.nasa.gov/19FZQq9

I found this article to be intriguing and wanted to share it.
Long stays in space have a major hitch. Medical studies on the effects of microgravity on astronauts after many months in low-Earth orbit (LEO) can’t get around one hard truth --- humans aren’t cut out for life without gravity. Thus, artificial gravity habitats are now being discussed as a crucial [...]

+Douglas Loscalzo No worries.. I always forget the /sarc... I just think that those who have been reading my stuff know that I'm a very sarcastic kind of guy. But, I do have my serious moments... Not often, because they raise my blood pressure. lol.

No, the way you explained things the first time was fine. I just found it rather funny, in my head. I think it was the sequence of your statement that my mind had some fun with... first "nailed down", then "move on". My mind was going, "if you are nailed down, how can you move on... You'd be held in place with a nail". My mind is funny that way. It wasn't you at all. It was all my interpretation. I meant no offense, whatsoever.

Didn't we just have a lunar eclipse a few weeks ago??? Is it that time of the month already??? Sorry, it was the blood red that made me think that. Sorry, ladies.

Astronomy Papers That Caught My Eye In Today's arXiv

There are 59 papers today (Wednesday), not counting replacements. There were quite a few papers on the slowing of the rotation of magnetars.

Topics: Metalicity & SN at z=1.49, Nova Ejecta, Making a Star Cluster

Metalicity & SN at z-1.49 http://arxiv.org/abs/1503.08822 Galaxies seem to have started out getting lots of metals in their cores and more slowly spreading that higher metal/Hydrogen ratio to the outer spiral arms over time. This is pretty difficult to measure at the moment. Bright light sources where we can see absorption lines are needed, but at z>1 not much is bright. Someday the E-ELT and similar telescopes will be able to just look and see supernovae at such distances, but for now, we have to wait for rare lensed supernovae, and this paper is about one such SN, and the galactocentric metalicity gradient for one face-on spiral galaxy at z=1.49.

Nova Ejecta http://arxiv.org/abs/1503.08840 Recurrent Nova T Pyxidis was observed erupting six times since 1890 and probably erupted once around 1866, but that 1866 eruption may have been the first, or at least the first after millenia of being quiet. We know this because when it erupted in 2011, Hubble was used periodically to check on how the light from that eruption reionized knots of material from the previous eruptions. This paper tells the story, and shows the images of the light echos.

Making a Star Cluster http://arxiv.org/abs/1503.09037 S254-S258 OB Complex is a large infrared dark cloud with interior filaments about 8000 light years from here. It contains many protostars and young stellar objects., and is showing us what an open cluster looks like before it is done being made. From this example we can see one instance of how efficient and rapid the process of forming stars is. It is currently forming about 30 solar masses of stars every million years.

The James Webb Space Telescope is comprised of some very large structures, and those have to fit together before, during, and after launch. Extreme care has to be taken when moving equipment that weighs thousands of pounds.

This episode of Behind the Webb gives us a glimpse into what it takes to test the compatibility between the backplane that will hold the primary mirror segments, the sunshield, and the spacecraft bus. We also see how the sunshield will be pulled into position, giving us a sense of how large the observatory will be when it's in orbit.

Typhoon Maysak strengthened into a super typhoon on March 31, reaching Category 5 hurricane status on the Saffir-Simpson Wind Scale. ESA Astronaut Samantha Cristoforetti captured this image while flying over the weather system on board the International Space Station. The Tropical Rainfall Measuring Mission (TRMM) and Global Precipitation Measurement (GPM) satellites, both co-managed by NASA and the Japan Aerospace Exploration Agency, captured rainfall and cloud data that revealed heavy rainfall and high thunderstorms in the strengthening storm. The TRMM satellite has been collecting valuable scientific data since November 1997. Early on March 30, the satellite collected rainfall data as it flew directly above Maysak at 04 14 UTC (12 14 a.m. EDT) when maximum sustained winds were near 85 knots (98 mph). Rainfall data was collected by TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments and showed heaviest rainfall southwest of the center, and in fragmented bands of thunderstorms northeast of the center. In both of those places rainfall was in excess of 50 mm/2 inches per hour. More information.

Grannymede has oceans, too! ... Jupiter moon’s underground saltwater explains Hubble telescope observations -- "Jupiter’s largest moon, Ganymede, has solidified its membership in the growing cadre of solar system locales where liquid water flows beneath the surface.

“The solar system is now looking like a pretty soggy place,” Jim Green, director of NASA’s Planetary Science Division, said March 12 at a news conference.

The ocean showed itself not with plumes or pools but via subtle changes in Ganymede’s aurora, the moon’s version of the Northern Lights. Jupiter’s magnetic field should interfere with Ganymede’s, causing the moon’s aurora to rock back and forth by about 6 degrees. Observations with the Hubble Space Telescope, however, showed that the aurora shifted by only about 2 degrees. Joachim Saur, a geophysicist at the University of Cologne, Germany, and colleagues deduced that an electrically conductive fluid beneath the surface — a saltwater ocean, for example — would create a secondary magnetic field that counteracted Jupiter’s interference.Observations with the Galileo probe, which orbited Jupiter from 1995 to 2003, hinted at Ganymede’s ocean ..."

Astronomers combined ultraviolet images of Saturn's southern polar region with visible-light images of the planet and its rings to make this picture. The auroral display appears blue because of the glow of ultraviolet light. In reality, the aurora would appear red to an observer at Saturn because of the presence of glowing hydrogen in the atmosphere.
