    From Platypus to Parsecs and MilliCrab: Why do Astronomers use such Weird Units?

    April 19, 2023, Categories  Astronomy/Space

    A bright, multi-coloured supernova remnant with dusty, wispy filaments and something resembling a tornado (the pulsar wind nebula) in the centre.

    You may have heard about an asteroid set to fly near Earth that is the size of 18 platypus, or maybe the one that’s the size of 33 armadillos, or even one the size of 22 tuna fish.

    These outlandish comparisons are the invention of Jerusalem Post journalist Aaron Reich (who bills himself as “creator of the giraffe...

    Footprints of Galactic Immigration uncovered in Andromeda Galaxy

    February 10, 2023, Categories  Astronomy/Space

    A team of researchers led by astronomers at NSF’s NOIRLab has uncovered striking new evidence for a mass migration of stars into the Andromeda Galaxy. Intricate patterns in the motions of stars reveal an immigration history very similar to that of the Milky Way. The new results were obtained with the DOE’s Dark Energy Spectroscopic Instrument on the Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory, a Program of NSF’s NOIRLab.

    Hubble Maps Giant Halo around Andromeda Galaxy

    August 30, 2020, Categories  Astronomy/Space

    This illustration shows the location of the 43 quasars scientists used to probe Andromeda’s gaseous halo. These quasars—the very distant, brilliant cores of active galaxies powered by black holes—are scattered far behind the halo, allowing scientists to probe multiple regions. Looking through the immense halo at the quasars’ light, the team observed how this light is absorbed by the halo and how that absorption changes in different regions. By tracing the absorption of light coming from the background quasars, scientists are able to probe the halo’s material.

    In a landmark study, scientists using NASA’s Hubble Space Telescope have mapped the immense envelope of gas, called a halo, surrounding the Andromeda galaxy, our nearest large g...

    The Milky Way’s Long-Lost Sibling finally found

    Scientists at the University of Michigan have deduced that the Andromeda galaxy, our closest large galactic neighbor, shredded and cannibalized a massive galaxy two billion years ago. Even though it was mostly shredded, this massive galaxy left behind a rich trail of evidence: an almost invisible halo of stars larger than the Andromeda galaxy itself, an elusive stream of stars and a separate enigmatic compact galaxy, M32...
