What is the Saraswati supercluster?

What is the Saraswati supercluster? What are galaxy clusters? How big are they? Galaxies are like the building blocks of the universe, they contain a huge number of stars, something like 100 billion at a count. Galaxy groups can have three to 20 galaxies, the richest systems are called clusters (like the Virgo cluster) which can have several hundred galaxies. Superclusters are clusters of clusters. They can have as few as two clusters, and superclusters with two to four clusters are common. Saraswati has 42. Within superclusters, clusters are connected by filaments and sheets of dark matter with galaxies embedded in them. It is supposed that the galaxies are born in the filaments and then migrate towards the intersection of the filaments where they are assimilated into clusters. What are superclusters?

St. Petersburg: White Nights calling

St. Petersburg: White Nights calling Whoever called New York “the city that never sleeps” had clearly never been to St. Petersburg in the summer. The Russian metropolis, which will host seven matches at next summer’s FIFA World Cup, is bathed in almost perpetual daylight between May and June.

As Indonesia cuts forests, fake nature thrives

As Indonesia cuts forests, fake nature thrives JAKARTA: Indonesia’s capital is lush with fake greenery even as the country is cutting down its precious tropical forests at a record rate. Jakarta’s gleaming air-conditioned malls have a particular fondness for lifeless extravaganzas of plastic ferns or autumnal trees that don’t drop any leaves. Construction sites are wrapped in screens printed with giant leaves glistening with dew drops or the picturesque deciduous forests found in temperate climates. A new terminal at the international airport has a mini-jungle within its cavernous air-conditioned interior. Despite the odd inclusion of fake grass it has the slight saving grace that the potted greenery is real. It’s not that Jakarta lacks real trees. The presidential palace has well-manicured surrounds of park, verges and trees. But elsewhere, against the backdrop of unrelenting traffic and brutalist concrete, the greens often seem weirdly out of place, like an introduced alien specie...
