An international team of astronomers found a dwarf galaxy in the outskirts of the Andromeda Galaxy, M31, located over 2.5 million light-years from us. However, the ultra-faint dwarf galaxy, now called Pegasus V, was first spotted by a very attentive amateur astronomer Giuseppe Donatiello, of UAI, the Unione Astrofili Italiani.
How do giant black holes shut off star formation? How do they turn it back on? Which came first, the black hole or the galaxy? I discuss these questions and more in today’s Ask a Spaceman!
Time for your June sky guide and news round up with @AwesomeAstroPod. This month we have A companion star that survived a supernova, dark matter stripped away in galaxies, and of course the image of Sagittarius A*.
News round-up with @WSHCrew this week will cover various topic including cosmic rays as earthquake detection, rare galaxies forming stars, James Webb, machine learning for exoplanet cartography, solar flares, and Event Horizon Telescope.
Time for @AwesomeAstroPod news round-up and skyguide. We have JWST, new type of nebula, detecting life in Europa, exoplanet around dead star, galaxy with no dark matter and more. #365DaysOfAstro
Today we bring you space scoop about the magnificent galaxy NGC 1566, nicknamed the “Spanish Dancer”. More at #365DaysofAstro
The Milky Way is a vast grand spiral today, but how did it get this way? Looks like ancient collisions with dwarf galaxies is the answer. But the ancient collisions with dwarf galaxies, and how they came together to build the modern Milky Way?
A recent image from the South African MeerKAT Telescope blew our minds. It was a high resolution image of the center of the Milky Way showing delicate filaments and other structures. Today we’re gonna talk about why this was such an accomplishment and what the future holds for radio astronomy.
Time for news update. The @WSHCrew discuss about gigantic galactic shock wave, what to see in the sky, JWST and alien detection, the hidden Supermassive black hole, and a dwarf galaxy.
Defying expectations, an ultramassive galaxy and many of its cluster companions had already formed most of their stars and become inactive only two billion years after the beginning of the Universe
