A cable anchored to the lunar surface would stretch most of the 400,000km (250,000 miles) home. It couldn’t be directly attached to the Earth, due to the relative motions of the two objects, but it could terminate high in Earth orbit. That would have the added benefit of placing it above the bulk of our…
The Soviet Union is leapfrogging into space. America is very busy. The competition for who comes first is fierce. The space mission carrying about twenty men is over. Now comes the important part. Docking or manned spacecraft. That is the most important training to land on the moon. The Atlas rocket carrying the Agena spacecraft…
In July 2006, a Gamma Ray Burst (GRB) was identified from a distance of 1.6 Billion Lightyears. It lasted 102 seconds, and although it was a common occurrence, the GRB had a special feature. If there is to be a GRB that lasts that long, it must be the result of a supernova. But no…
From the history of science we can find many revolutions that have changed and corrected human perceptions of the universe. Through Copernicus, a revolution took place that established a heliocentric world instead of a world centered on the earth. Earth was transformed into a small planet orbiting the star Sun. Later, man saw a new…
But a deeper exposure and a much more careful processing will reveal that these galaxies, far from being visualized against a nearly dark, empty background, they are surrounded by huge clouds of dust…The truth is that the galaxies are not surrounded by this dust – the dust is much closer to us than the galaxies…
After nearly 20 years of development and 16 launch delays, the James Webb Space Telescope (JWST) is almost ready. Set to launch on 31 October 2021, the largest space observatory ever built is set to revolutionise our understanding of the cosmos and help solve some of the Universe’s greatest mysteries.Instead or orbiting the Earth, Webb…
At 4 billion light-years in length, the Large Quasar Group (LQG) is the largest known structure in the universe and is some 1600 times larger than the distance from the Milky Way to Andromeda.
Chandrayaan 2 Orbiter has been sending high resolution images of the Moon and other scientific data to Earth for two years. ISRO is conducting an online Lunar Science Workshop on Septemper 6-7. In addition, data and images collected by Chandrayaan 2 orbiter will be made available in the public domain. Chandrayaan 2 was mentioned in…
Look at the two pictures given to make this clear. The first is when someone throws a stone. The velocity of the stone is shown as two elements, vertical and horizontal. Since there is no force in the opposite direction to the coastal component, the stone travels away until it falls to the ground. As…
Plasma with high brightness is a giant sphere held together by gravity. The Sun is the closest star to the Earth, and is the source of most of the Earth’s energy. The stars appear when other atmospheric phenomena are uninterrupted during the night when the sun is absent. Historically, some of the major stars in…
