NASA’s Spitzer Science Center: “Ask An Astronomer (Part 2) Where Stars Are Born – W-5 Star-Forming Region”. In this popular video series, real astronomers answer common questions about astronomy. Brought to you by the “Cool Cosmos” team (the joint Education and Public Outreach group for the Spitzer Space Telescope and the Infrared Processing and Analysis Center) located at the California Institute of Technology in Pasadena, California. Narrated by Dr. Robert Hurt of NASA’s Spitzer Science Center. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com — How do stars form? A study of star forming region W5 by the sun-orbiting Spitzer Space Telescope provides clear clues by recording that massive stars near the center of empty cavities are older than stars near the edges. A likely reason for this is that the older stars in the center are actually triggering the formation of the younger edge stars. The triggered star formation occurs when hot outflowing gas compresses cooler gas into knots dense enough to gravitationally contract into stars. Spectacular pillars, left slowly evaporating from the hot outflowing gas, provide further visual clues. In the above scientifically-colored infrared image, red indicates heated dust, while white and green indicate particularly dense gas clouds. W5 is also known as IC 1848, and together with IC 1805 form a complex region of star formation popularly dubbed the Heart and Soul Nebulas. W5 lies about …

Hubblecast 31: Sky merger yields sparkling dividends. A recent NASA/ESA Hubble Space Telescope image captures what appears to be one very bright and bizarre galaxy, but is actually the result of a pair of spiral galaxies, like our own Milky Way smashing together at breakneck speeds. The product of this dramatic collision, called NGC 2623, or Arp 243, is about 250 million light-years away in the constellation of Cancer (the Crab). This object was a target of Hubble’s and a handful of its “sibling” spacecraft as part of a massive comprehensive sky survey called GOALS. — • www.youtube.com • www.youtube.com — Not surprisingly, interacting galaxies have a dramatic effect on each other. Studies have revealed that as galaxies approach one another massive amounts of gas are pulled from each galaxy towards the centre of the other, until ultimately, the two merge into one massive galaxy. The object in the image, NGC 2623, is in the late stages of the merging process with the centres of the original galaxy pair now merged into one nucleus. However, stretching out from the centre are two tidal tails of young stars showing that a merger has taken place. During such a collision, the dramatic exchange of mass and gases initiates star formation, seen here in both the tails. The prominent lower tail is richly populated with bright star clusters — 100 of them have been found in these observations. The large star clusters that the team have observed in the merged galaxy are brighter …

Interesting video with deep space images along with images of our own solar system. *There are 167 known moons in our Solar System: Mercury does not have any natural satellites moons. Venus does not have any natural satellites moons. Mars has 2 natural moons. Jupiter has 63 natural moons. Saturn has 61 natural moons, and over 150 ‘moon-lets’. Uranus has 27 natural moons. Neptune has 13 natural moons.

Hubble Space Telescope’s Near Infrared Camera and Multi-Object Spectrometer (NICMOS) joins forces with the Spitzer Space Telescope to peer deeper into the Milky Way’s center. Hubble detected a new population of massive stars about 26000 light-years away. Astronomers can use this data to study how these stars form and influence their environment.

I just observed Comet McNaught during the day! I made a video blog about this comet the other day, and make a couple of corrections, and give some hints on how to see this daylight spectacle.
