Astronomers identify dozens of new Beta Cephei stars

Using the Kilodegree Extremely Little Telescope (KELT), astronomers have detected 86 new Beta Cephei (β Cep) stars in the Milky Way galaxy. The discovery, detailed in a paper published July 26 on the arXiv pre-print repository, greatly improves the number of galactic β Cep stars known to date.

Astronomers map our local cosmic void

Our universe is a tapestry of galaxy congregations and vast voids. An international team of astronomers has now published a new study revealing more of this cosmic structure as it appears surrounding our Milky Way. Source: https://earthsky.org/space/tully-cosmicflows-3-local-void…

When our Milky Way merged with an ancient dwarf galaxy

Analysis of measurements via the Gaia space telescope – of star positions, brightnesses and distances – has let astronomers probe a merger 10 billion years ago between the primitive Milky Way and a dwarf galaxy called Gaia-Enceladus.

A 3-D model of the Milky Way Galaxy using data from Cepheids

A team of researchers at the University of Warsaw has created the most accurate 3-D model of the Milky Way Galaxy to date. In their paper published in the journal Science, the group explains how they used measurements from a special group of pulsating stars to create the map.

Dark Rift in the Milky Way

Standing under a dark sky in late July or August? Look up! You’ll notice a long, dark lane dividing the bright Milky Way. This Dark Rift is a place where new stars are forming. Source: https://earthsky.org/clusters-nebulae-galaxies/the-great-rift-in-the-milky-way…

See the constellation Scutum the Shield

Scutum has only has 4 stars that make up the constellation outline, but it’s noticeable in a dark sky because a rich region of the Milky Way is behind it. Source: https://earthsky.org/tonight/constellation-named-for-a-polish-king-2…

The black hole disk that shouldn’t exist

Astronomers didn’t expect to see a thin disk around the supermassive black hole at the center of galaxy NGC 3147, some 130 million light-years away. They’re using Einstein’s theories of relativity to understand the velocities involved, and the intensity of black hole’s pull.

Find M4 near the Scorpion’s Heart

If you’ve never found a deep-sky object on your own before, M4 – a globular star cluster, one of the nearest to our solar system – is a grand place to start. It’s near the bright red star Antares in the easy-to-spot constellation Scorpius the Scorpion. To spot it, you’ll need a dark sky.
