An earth-sized telescope
Black holes occur in the middle of galaxies where mass collapses to form gravity-dense regions. Anything that falls into a black hole cannot escape — not even light, making it impossible to see black holes directly.

The science behind potholes
Come monsoon, and we seem to encounter and embrace ourselves to manoeuvring the dreaded potholes on our streets. Every year, disgruntled citizens take on the civic authorities for the rise in the number of potholes and the threat it poses to motorists. Worldwide, roads seem to be prone to potholes wherever asphalt is used in their construction. The nature of asphalt (or bitumen) allows binding that can sustain significant plastic deformations. However, a combination of unscientifically laid roads and their continuous wear can result in potholes.

Did You Know? Light and night vision
As the sun sets and it dawns, we humans perceive it becomes dark with no natural light. At best, we use other light sources to illuminate our surroundings for continuing our activities at night. This is because as humans, we can perceive light only in a particular spectrum of the electromagnetic radiation, which is called as visible light. Technically, light is any radiation across various wavelengths in the electromagnetic spectrum. And a portion of it, having a wavelength within 400-700 nanometres, falls under the category, which is what our eyes have evolved to perceive (sense).

6 facts about Venus
Hostile environment: Venus is a terrestrial planet with rocky terrain, volcanoes, and a dense atmosphere. Carbon dioxide and sulphuric acid-laden clouds dominate the dense atmosphere which also gives rise to excruciating surface pressures of 92 bars (as much as that at 1km below sea level on earth), making the planet inhospitable.
