Indian astronomers discover giant cosmic web filament stretching 8.5 lakh light years

Pune-based PhD scholar Eshita Banerjee-led international team of astronomers discovered a cosmic web filament stretching nearly 8.5 lakh light years, roughly 10 times the size of Milky Way galaxy's disk. A cosmic web is collection of invisible streams of gas and dark matter that theoretically connect different galaxies. Such filaments have densities 100 billion trillion lower than our atmosphere.
