Galaxy

This image shows a section of the side view of the Milky Way as measured by ESA’s Gaia satellite. The dark band consists of gas and dust, which dims the light from the embedded stars. The Galactic Centre of the Milky Way is indicated on the right of the image, shining brightly below the dark zone. The box to the left of the middle marks the location of the “Maggie” filament. It shows the distribution of atomic hydrogen. The colours indicate different velocities of the gas. [less] Image: ESA/Gaia/DPAC, CC BY-SA 3.0 IGO & T. Müller/J. Syed/MPIA

Meet Maggie, the longest structure in our galaxy

Meet Maggie, a huge filament of atomic hydrogen just discovered by astronomers, a possible precursor to star formation. It is the largest structure yet found in the Milky Way Galaxy.

Stars moving around the black hole Sag A*: these images were taken between March and July 2021 and show stars orbiting very close to Sagittarius A*. During the observations, one of these stars, S29, reached its closest approach to this supermassive black hole at the heart of the Milky Way; the distance was 13 billion kilometres, which is just 90 times the distance between the Sun and Earth. In addition, the researchers discovered another star, S300, with the Gravity Instrument at the European Southern Observatory's Very Large Telescope Interferometer (VLTI).

Deep View of Supermassive Blackhole Sag A* at the centre of Milky Way

Here is a Deep View of Supermassive Blackhole Sag A* at the centre of our Milky Way galaxy. Scientists also saw new stars whizzing around it.

The galaxy AGC 114905. The stellar emission of the galaxy is shown in blue. The green clouds show the neutral hydrogen gas. The galaxy does not appear to contain any dark matter, even after 40 hours of detailed measurements with state-of-the-art telescopes. Credit: (c) Javier Román & Pavel Mancera Piña

Can there be galaxies without dark matter?

Can there be galaxies without dark matter? A new study says yes. Astronomers found 6 galaxies with little or no dark matter.

A Planet in another Galaxy

A Planet has been found in Galaxy M51 also known as the Whirlpool Galaxy. This is the first time such a planet has been found outside the Milky Way.

Collage of carvings on deer bones by Neanderthals from 51,000 years ago and image showing the formation and evolution of the first stars and galaxies in a virtual universe similar to our own. Posted by 360 on History

Podcast Episode 37 l Ancient Humans and Ancient Stars

We are talking about two things today, one from thousands of years ago and the other millions of years. First we talk about ancient carvings made by Neanderthals, and then about the age of the oldest ...

Hubble Turns 31 Celebrates with Giant Exploded Star

Hubble Turns 31 Celebrates with Giant Exploded Star in this amazing image and video. AG Carinae is a Luminous Variable Star that exploded 1000s of years ago

Images of the Milky Way and the Large Magellanic Cloud (LMC) are overlaid on a map of the surrounding galactic halo. The smaller structure is a wake created by the LMC’s motion through this region. The larger light-blue feature corresponds to a high density of stars observed in the northern hemisphere of our galaxy. Credits: NASA/ESA/JPL-Caltech/Conroy et. al. 2021
