#JamesWebbSpaceTelescope's new photo of the Tarantula Nebula caught thousands of never-before-seen baby stars

#NASAWebb… Image
Astronomers focused the #JamesWebbSpaceTelescope on Tarantula Nebula, one of the brightest and most active star-forming regions in our galactic backyard, and found thousands of young stars they hadn't seen before, images released by NASA on Tuesday show.…
The Tarantula Nebula, is an immense cloud of gas and dust about 160,000 light-years away in the Large Magellanic Cloud, a satellite galaxy of the #MilkyWay. The nebula has birthed some massive stars, a few that are more than 150 times the mass of our sun.…

📢 Breaking news: Meet the Black Hole at the Centre of our Galaxy! Astronomers have unveiled the 1st image of the supermassive black hole at the centre of the Milky Way. The image was produced by a global research team @ehtelescope 📷EHT Collaboration
“It is very exciting for ESO to have been playing such an important role in unravelling the mysteries of black holes, and of Sgr A* in particular, over so many years,” commented ESO Director General @xbarcons 👇
“ESO not only contributed to the EHT observations through the ALMA and APEX facilities but also enabled, with its other observatories in Chile, some of the previous breakthrough observations of the Galactic centre.”

A diffuse glow of high-energy gamma rays hints at the presence of powerful cosmic accelerators, called PeVatrons, within the disk of our Galaxy.

#Space #Astrophysics
Many physicists believe that such #PeVatrons accelerate particles up to at least PeV energies (PeV=10^15 eV).

Possible PeVatrons include #supernova explosions, star-forming regions, & Sgr A* the supermassive black hole at the center of our galaxy.

#Space #Astrophysics
But despite decades of hunting, only a few PeVatron candidates have been located in the #MilkyWay.

The Tibet ASγ experiment, a #China-#Japan collaboration, has reported new measurements that provide further evidence for galactic #PeVatrons.

#Space | It took over a decade and 1,000 hours of photography to create this picture of the #MilkyWay…

By @pabsgill
@pabsgill Finnish astrophotographer, JP Metsavainio, took on the daunting task of creating a mosaic of the #MilkyWay back in 2009. It took him twelve years to get the whole picture which is around 100,000 pixels wide and has 234 individual mosaic panels stitched together.

@pabsgill "The reason for a long time period is naturally the size of the mosaic and the fact that the image is very deep. Another reason is that I have shot most of the mosaic frames as individual compositions and published them as independent artworks.," Metsavainio wrote on his blog.

I'm beginning tweeting at the #wintersolstice

As I just explained, we just finished building a new monument, #soultonlongbarrow, which revives a prehistoric practice of building long barrows, not seen for 5,500 years

These are the first images of the new chamber ever shared ImageImageImageImage
Im going 2 explain more about what this is, and how it has been an important resource for our community in surprising ways in this challenging covid year, but for now, I just wanted to share a picture of the monument working with the #wintersolstice #sunset for the 1st time today Image
Now, I realise I need to expand aspects of the context for this happening.

Let's start around 5,500 years go, when the first farmers in the British Isles also found #architecture, which they do by building long barrows... Here's West Kennet in Wiltshire (📸 from resarch trips) Image

New #Milkyway Map Show #Earth 2,000 Light Years Closer to Massive #BlackHole Than Previously Thought…

By- @MrigDixit

(📸: NASA/JPL-Caltech/R. Hurt (SSC/Caltech))
A new cosmic map has suggested that the #Earth is spiralling 2,000 light-years closer to the #BlackHole located at the centre of our #MilkyWay galaxy.Dont worry,our planet is not plunging into the black hole soon as it is still thousands of light-years away from the black hole.
The new map constructed by the #astronomers from the National Astronomical Observatory of Japan (NAOJ) is developed using data collected over the past 15 years. It places #Earth just 25,800 light-years away from the centre of the galaxy where the #BlackHole resides.

#MilkyWayGalaxy Hosts At Least 30 Crore Potentially Habitable Planets; Closest Around 20 Light-Years Away - by @MrigDixit…

(📸: NASA Ames/JPL-Caltech/T. Pyle)
For starters, an #Earth-like planet is essentially any planet that is rocky, roughly the same size as the Earth, and orbiting a G-type star—often called a yellow dwarf star—like the Sun.
The planet must also be orbiting at the 'Goldilocks’ distance—positioned in the habitable zone around the star—in order to be able to host liquid water, and potentially life, on its surface.

Astronomers Spot Six Galaxies Trapped Around Supermassive #BlackHole in Spider Web-Like Structure - by @MrigDixit…

(📸: ESO/L. Calçada)
Nothing can escape the powerful cosmic monster black holes—not even light—due to its strong gravitational pull that attracts nearly everything around the region.

But for the first time, astronomers have spotted six galaxies trapped around a supermassive black hole, appearing to form a spider web-like structure.

.@NASAHubble telescope captured a stunning photo of the distant spiral galaxy named 'Eye of the Serpent'

#NASA @NASA #ESA @esa ImageImageImage
A spiral galaxy nicknamed "Eye of the Serpent" is 35 million light-years from #Earth. The Hubble Space Telescope recently snapped a photo of the #galaxy, which is about half the width of the #MilkyWay and has a supermassive black hole at its center.

@NASA @NASAHubble @esa
Its distinct arms, where stars and gas are compressed, create the illusion of an eye — which is why astronomers call it the "Eye of the Serpent."

#Astronomers Discover First Look-Alike of Our #MilkyWay Galaxy in Early Universe…

(📸: ESA/Hubble/NASA, A. Riess et al)

By @MrigDixit Image
Astronomers have spotted a look-alike galaxy our Milky Way with a close resemblance.

The newly found galaxy named SPT0418-47 is estimated to be located about 12 billion light-years from our galaxy, it is so far that its light takes nearly 12 billion years to travel & reach us.
The newly discovered galaxy was formed when the universe was just 10% of its current age—about 1.4 billion years old.

A galaxy comprises gas, dust & billions of stars—held together by gravity. Milky Way galaxy that holds the entire solar system—is about 13.51 billion years old.

A new 3D map of the #MilkyWay reveals our galaxy's warped shape in unprecedented detail…
Researchers at the University of Warsaw in Poland measured the distances between thousands of stars and our sun to chart the stars' three-dimensional coordinates across the Milky Way.
The result is an unprecedented large-scale 3D map of the galaxy. And that map shows that the edges of the Milky way bend slightly, giving it a warped S shape.

I'm wondering if it's possible to use the @ehtelescope to find out more about the #WowSignal.
And while we are talking about the #WowSignal: I have an alternative speculation for it besides aliens (although I still think it actually has a natural cause we haven't found yet, so don't get too excited): us from a parallel timeline somehow sending a spacecraft in the past.
There are possible indications why it could be us and not aliens. The first indication is that the #WowSignal didn't last long. If it really was aliens trying to contact us then why did they seemingly only send this signal for a short time and not continuously?
