Recent Observations 18
Recently, I have gone out to see the winter constellations and the moon once again. I saw the first quarter moon on Wednesday, 2/25/15. I managed to find Orion and pinpoint many other winter constellations I know after that (including Auriga, Lepus, Columba, and others). The sky was not completely clear and a bit drizzly where I was but I still managed to see quite a bit of stars.

Love and War by Moonlight
Love and War by Moonlight
Venus (Roman goddess of love) and Mars (war god) came together by moonlight in this image taken on February 20 (Charleston, South Carolina). In the picture the moon is crescent and the way this image was taken allows earth shine to illuminate the otherwise dark surface of the Moon. Despite the fact that this triple conjunction has already pasted, Venus remains in the west (third brightest object in sky- after Sun and Moon). The much fainter Mars approached closer on the following evening but has since been moving slowly away from Venus (visible in western sky still).

On Valentine's Day I went out star gazing. I managed to point out many constellations due to the sky being very clear and being in a less lit area. I pinpointed Orion and from there on I was able to spot Aurgia, Taurus, Lepus, Columba, Eridanus, Fornax and other winter constellations surrounding the famous stars of Orion's Belt.

Fibrils Flower on the Sun
There are times the sun may resemble a rose, such as when a specific color of red light emitted by hydrogen. The pinkish color is seen on some regions of the solar chromosphere. The color-inverted image was taken in October 2014 and displays the active solar/sunspot region 2177 (which survived several days before evolving yet again) on the sun. The "petals" are actually magnetically confined tubes of hot plasma (known as fibrils - some of which extend longer than the diameter of the Earth). Due to the way this picture was taken, the central region fibrils are seen end-on and surrounding regions are filled with curved fibrils (huge plasma tubes seen over the Sun's edge- spicules,when in passive regions- mottles).

I went out 2/9/2015 to see the sky. The moon was in a waning gibbous phase, leading away from being a full moon and heading to be a new moon phase. There was not many interesting things happening that night so I just focused on observing the constellations such as Orion (by finding Orion's Belt) and then observing where I believed Taurus, Eridanus, and Auriga were.

Layered Rocks near Mount Sharp on Mars
The leading hypothesis about how these rocks on Mars became layered is due to an ancient Martian lake that kept evaporating and refilling over 10 million years. Today, this lake has remained dry and empty of water for billions of years. This image was taken last November by the Curiosity rover and the picture shows the one-meter wide Whale Rock (part of the Pahrump Hills outcrop at the base of Mount Sharp). The rocks display cross-bedding (rock with angled layers) which were likely facilitated by waves of sand.

On Tuesday night I went outside at about 7:00pm in order to observe the HST. The HST began at 7:10 and lasted 7 minutes (occurred to the West). At 7:18, I was able to see the space station in the Southwest for 5 minutes. The moon was a full moon which was pretty bright when attempting to find constellations but I was able to find Orion's Belt and with it, Orion.

Jets from Comet Churyumov-Gerasimenko
The image above is one of the best images of emerging jets (taken last November by Rosetta spacecraft). The comet above is 67P/Churyumov-Gerasimenko (Comet CG), the picture is overexposed, and when observing the image, one can see plumes of gas and dust escaping numerous places from the nucleus (occurring because it is nearing the sun and heating up). In August, the orbit on the comet will take it almost as close to the sun as the Earth is and its jet activity is expected to increase by about 100.
