Milky Way Views

Post by Christopher K. »

I know this is at least six months late, but a post in the General Discussion section prompted me to expand on the topic.

With yellow as Hubble's near-infrared, red as Spitzer's infrared, and blue and violet as Chandra's x-ray detection, this color-coded composite of the center of our galaxy is mindblowing. The x-rays are million of degrees hot. The image was unveiled as part of the IYA2009 celebration last year.

I guess we can consider ourselves lucky to be 30,000 light years from the center so we can have this perspective. The optical view in a dark sky is, needless to say, amazing.

Last Tuesday's APOD is an unusual fisheye of our Galaxy taken from Te Mata Peak in New Zealand. The red tint seen in the sky is not light pollution but airglow.

A 2 March image taken from Pensacola Beach by Kenny Alexander is slide number ten in the collaborative gallery from Time Magazine and the Astronomical League. There are streaks emanating from the center of the image. I suppose they could be meteor streaks, but they look odd. Furthermore, there are no major meteor shower that peak in March.

The 26 January APOD is an image of Sergei Makurin's made in February 2014, showing the Milky Way stretched above the Seven Strong Men formation near the Ural Mountains. I assume the intense yellow glow at the bottom left indicates sunrise.

The 27 January APOD is courtesy the ESA mission called Planck (named for the famous German theoretical physicist). The image span thirty degrees and is a stylized map of our Galaxy's magnetic field.

The 23 February APOD shows the band of our home galaxy capping the Toadstool formations in Arizona. These Toadstools are seventy-two kilometers east of Kanab and nineteen kilometers west of Big Water--for those who will find themselves out that way one day.

Spitzer is well-known for using its infrared gaze to penetrate cool gas and dust to see the view beyond. That's exactly what it did with the core of our home galaxy.

A poster recently praised Yuri Beletsky's photography. Babak Tafreshi is another picture-taker whose output is consistently high-quality. This 13 July pic shows the outline of Ayers Rock. Since the Rock isn't purposely illuminated (which I guess would be a feat!) I don't know if this is a combination of two exposures or not.

Radio filaments called the Arc are very near the center of the Milky Way galaxy. I wonder what their sound on an appropriately-tuned radio would resemble. Chandra and MeerKAT both contributed to this wonderful multiple-wavelength image...

It may be a "false" view (I guess you can't really see mountain peaks illuminated by sunset while simultaneously catching the Milky Way in a nearly-dark sky) but it is intriguing and pretty. Digital technology can create some good special effects...
