Extreme Close-Up of the Face on Mars

Here's a picture you probably won't see in the tabloid racks while waiting in line at the grocery store. This is the famous "Face on Mars," and is the closest image ever of the this landform, taken by the best Mars camera ever, HiRISE on the Mars Reconnaissance Orbiter. And it certainly looks like …. the top of mesa, which is exactly what it is. This feature in the Cydonia region of Mars is most likely a lava dome that has created an isolated mesa or butte-like structure, i.e., a hill. Compare this image to the original image from the Viking orbiter from 1976 image, below, which created such a furor, including a whole new culture of conspiracy theories, books, late-night radio talk show discussion and even a full-length feature film. Alas, its just a hill.

New Geek Destination: Klingon Cave Tours

Klingon vanity license plate, via Charven.com

Since "Star Trek: The Experience" is no longer open, here's the next best thing. A company is getting ready to provide self-guided tours of the Jenolan Caves west of Sydney, Australia, and one of the languages soon available for the tours is Klingon. Yes, it is a fictional, completely fabricated Star Trek language, but I'm guessing there will be some takers on this. Why Klingon?

Where In The Universe Challenge #113

It’s time once again for another Where In The Universe Challenge. This image was sent in by UT reader Brian Hinson. Name where in the Universe this image was taken and give yourself extra points if you can name exactly what it is. Post your guesses in the comments section, and check back on later at this same post to find the answer. To make this challenge fun for everyone, please don’t include links or extensive explanations with your answer. Good luck!

This Week in Space — Apollo-Soyuz Anniversary Edition

I missed posting the latest "This Week in Space" with Miles O'Brien, but it is a special edition that takes a look at the 35th anniversary of Apollo-Soyuz project with exclusive interviews, and more. There's also a look at Virgin Galactic's latest test flight and a look at the latest of what's going in Congress with NASA's budget.

Stunning New Image of Wolf-Rayet Star and the Carina Nebula

Massive stars live fast and die young. But they are also beautiful. This amazingly spectacular new image from ESO shows the brilliant and unusual star Wolf-Rayet 22 nestled within billowing, colorful folds of the Carina Nebula. WR 22 is one of many exceptionally hot and brilliant stars contained by the beautiful Carina Nebula (also known as NGC 3372), a huge region of star formation in the southern Milky Way. The image was captured by ESO’s Wide Field Imager at the La Silla Observatory in Chile.

Into the Looking Glass
Recently, technicians at NASA's Marshall Space Flight Center in Huntsville, Ala., completed a series of cryogenic tests on six James Webb Space Telescope beryllium mirror segments at the center's X-ray & Cryogenic Facility. During testing, the mirrors were subjected to extreme temperatures dipping to -415 degrees Fahrenheit, permitting engineers to measure in extreme detail how the shape of the mirror changes as it cools. The Webb telescope has 18 mirrors, each of which will be tested twice in the Center's X-ray & Cryogenic Facility to ensure that the mirror will maintain its shape in a space environment -- once with bare polished beryllium and then again after a thin coating of gold is applied. The cryogenic test gauges how each mirror changes temperature and shape over a range of operational temperatures in space. This helps predict how well the telescope will image infrared sources. The mirrors are designed to stay cold to allow scientists to observe the infrared light they reflect using a telescope and instruments optimized to detect this light. Warm objects give off infrared light, or heat. If the Webb telescope mirror is too warm, the faint infrared light from distant galaxies may be lost in the infrared glow of the mirror itself. Thus, the Webb telescope's mirrors need to operate in a deep cold or cryogenic state, at around -379 degree Fahrenheit. Image Credit: NASA
