With your microwave!
I have almost this exact microwave. That’s it! I’m going to town for chocolate.
What a great science fair project!

Plumes of unknown origin over Mars have been photographed. The plumes seen in in images taken March and April of 2012. The images prompted a review of Hubble images of Mars and sure enough an image was found from 17 May 1997.
These are not the clouds occasionally imaged at about 100 km in the atmosphere, this phenomenon is seen at 250 km.
“At about 250 km, the division between the atmosphere and outer space is very thin, so the reported plumes are extremely unexpected,” says Agustin Sanchez-Lavega of the Universidad del País Vasco in Spain, lead author of the paper reporting the results in the journal Nature.
Wow! Look at that! Click the image for the larger version and take it in.
You can see the zoomable version at Hubblesite.
NASA’s Hubble Space Telescope has revisited the famous Pillars of Creation, revealing a sharper and wider view of the structures in this visible-light image.
Astronomers combined several Hubble exposures to assemble the wider view. The towering pillars are about 5 light-years tall. The dark, finger-like feature at bottom right may be a smaller version of the giant pillars. The new image was taken with Hubble’s versatile and sharp-eyed Wide Field Camera 3.
The pillars are bathed in the blistering ultraviolet light from a grouping of young, massive stars located off the top of the image. Streamers of gas can be seen bleeding off the pillars as the intense radiation heats and evaporates it into space. Denser regions of the pillars are shadowing material beneath them from the powerful radiation. Stars are being born deep inside the pillars, which are made of cold hydrogen gas laced with dust. The pillars are part of a small region of the Eagle Nebula, a vast star-forming region 6,500 light-years from Earth.
The colors in the image highlight emission from several chemical elements. Oxygen emission is blue, sulfur is orange, and hydrogen and nitrogen are green.
This really isn’t astronomy but I really liked the video. Must have been a sight to see!
The five test and development A350-900s took to the skies for a formation flight in September 2014, bringing together all of the aircraft used for Airbus’ successful campaign leading to certification of this latest Airbus widebody jetliner.
The Voyager 1 spacecraft is still returning science data. When the Sun lets off a Coronal Mass Ejection or CME that wave moves outward. It can be responsible for auroral displays on Earth and even Jupiter and Saturn. The waves or what are termed “tsunami waves” go into interstellar space. The Voyager 1 spacecraft recently experienced three such waves beginning in February 2014. The video is a sound depiction of ionized matter interacting with the CME and “ring like a bell”.by
A TED Talk. It isn’t the solstice video I was intending to put up, but I liked it better.
Yes it’s a solstice day!
The December solstice is here. The solstice occurs in a few hours at 23:03 UTC. The calendar day would be 21 or 22 December depending on your location.
For me, it is the shortest day of the year and after a short pause the day’s light will slowly lengthen. The road to spring is long and as a well known old-time weather man around here used to say: “As the days grow longer the cold grows stronger”.

I wouldn’t have thought warm gas would be like putting water on a fire:
A new feature in the evolution of galaxies has been captured in this image of galactic interactions. The two galaxies seen here — NGC 3226 at the top, NGC 3227 at the bottom — are awash in the remains of a departed third galaxy, cannibalized by the gravity of the surviving galaxies. The surge of warm gas flowing into NGC 3226, seen as a blue filament, appears to be shutting down this galaxy’s star formation, disrupting the cool gas needed to make fresh stars.
The findings come courtesy of the European Space Agency’s Herschel space observatory, in which NASA played a key role, and NASA’s Spitzer and Hubble space telescopes.
Adding material to galaxies often rejuvenates them, triggering new rounds of star birth as gas and dust gel together. Yet data from the three telescopes all indicate that NGC 3226 has a very low rate of star formation.
