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

@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.

Farmers Of The UK

@FarmersOfTheUK

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

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

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)

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

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

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.

#BlackHole

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

@NASA

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

@NASA

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

By @MrigDixit

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.

வானத்தை பார்த்துக்கொண்டே ஒரு அடி தூரத்தில் நம்ம கட்டை விரலை வைத்து அந்த இடத்தில் மட்டும் கண் பார்வையை தடுக்கிறோம் என்று வைத்துக்கொள்ளுங்கள், அந்த கட்டைவிரல் அளவுள்ள வானத்தில் அருகிலும், தூரத்திலுமாக ஆயிரக்கணக்கான கேலக்சிகள் உள்ளன.

நாம் இருப்பது Milky Way என்னும் கேலக்சி. மொத்தம் நமது டெலஸ்கோப்புகள் பார்வையிட முடிந்த பிரபஞ்சத்தில் (Observable universe) கிட்டத்தட்ட 200 பில்லியன் (200,000,000,000 - இரண்டு லட்சம் கோடிகள்) கேலக்சிகள் இருக்கலாம் என்பது அனுமானம்.

#Universe #Aliens 3/n
நாம் இருக்கும் Milky Way அப்படி ஒரு கேலக்சி. சூரியன் அதில் ஒரு நட்சத்திரம். இந்த Milky Way இல் மட்டும் சூரியனை போல 100 முதல் 400 பில்லியன் நட்சத்திரங்கள் இருக்கலாம். அதில் சூரியனை போல எல்லாவற்றுக்கும் கோள்கள் இருக்கவேண்டிய அவசியம் இல்லை.
