Comet ISON is heading for a Thanksgiving Day brush with the sun, but first it's going to pay a visit to the Red Planet. Mars rovers and satellites will have a ringside seat for the comet's close approach on Oct. 1st.
Astronomers have used observations from Hubble’s CANDELS survey to explore the sizes, shapes, and colours of distant galaxies over the last 80% of the Universe’s history. In the Universe today galaxies come in a variety of different forms, and are classified via a system known as the Hubble Sequence — and it turns out that this sequence was already in place as early as 11 billion years ago.
Astronomers using the NASA/ESA Hubble Space Telescope have solved the 40-year-old mystery of the origin of the Magellanic Stream, a long ribbon of gas stretching nearly halfway around the Milky Way. New Hubble observations reveal that most of this stream was stripped from the Small Magellanic Cloud some two billion years ago, with a smaller portion originating more recently from its larger neighbour.(read more)

New observations from the ALMA telescope in Chile have given astronomers the best view yet of how vigorous star formation can blast gas out of a galaxy and starve future generations of stars of the fuel they need to form and grow. The dramatic images show enormous outflows of molecular gas ejected by star-forming regions in the nearby Sculptor Galaxy. These new results help to explain the strange paucity of very massive galaxies in the Universe. The study is published in the journal Nature on 25 July 2013.(read more)
Try to imagine the people of the world: their wishes, dreams, and hopes for success or peace. Everyone. Imagine if we could see them all together, at the same time, looking up on their terraces or roofs, looking out their windows, or looking to the open sky in the fields, on the decks of ships or the tops of mountains. Think of them with their nose pointed up at the stars, each with their own wish ready to be made.
