    Star Birth with a chance of Winds?

    January 28, 2017, Categories  Astronomy/Space

    The lesser-known constellation of Canes Venatici (The Hunting Dogs), is home to a variety of deep-sky objects -- including this beautiful galaxy, known as NGC 4861. Astronomers are still debating on how to classify it. While its physical properties -- such as mass, size and rotational velocity -- indicate it to be a spiral galaxy, its appearance looks more like a comet with its dense, luminous 'head' and dimmer 'tail' trailing off. Features more fitting with a dwarf irregular galaxy. Credit: ESA/Hubble & NASA

    The dynamic space environment that surrounds Earth – the space our astronauts and spacecraft travel through – can be rattled by huge solar eruptions from the sun, which spew giant clouds of magnetic energy and plasma, a hot gas of electrically charged particles, out into space. The magnetic field of these solar eruptions are difficult to predict and can interact with Earth’s magnetic fields, causing space weather effects.

    345,000 or less chimpanzees remain in the wild, according to the International Union for the Conservation of Nature, a substantial decline from the more than 2 million that existed a hundred years ago. Humans’ closest genetic cousins, chimpanzees are an endangered species and scientists and conservationists are turning to the NASA-U.S. Geological Survey Landsat satellites to help bolster their efforts to preserve their forest homes...

    Rapid Gas Flares discovered in White Dwarf Star for the first time

    January 27, 2017, Categories  Astronomy/Space

    In February 2016 the dwarf nova SS Cyg anomalous outburst lasted for more than 3 weeks. Rapid radio flaring was seen throughout the outburst and the most intriguing behavior was towards the end of the outburst, where a fast, luminous, giant flare, peaking at ~20 mJy and lasting for 15 minutes was observed. This is the first time that such a flare has been observed in SS Cyg. Rapid flares are defined as a sudden,rapid, and intense variation in brightness.

    Incredibly rapid gas flares from a white dwarf binary star system have been detected for the first time by Oxford University scientists. The first sighting of such activity, it suggests that our current understanding of star habits and their capabilities is incomplete...
