Pollen grains are incredibly durable because they are made of an organic substance (called sporopollenin) that is very resistant to decay. Pollen is released into the air, often in large quantities, and can settle on surfaces like lakes, and become preserved in sediment deposits over thousands, or even millions, of years. | Photo Credit: M….
Microbes are an integral part of most, if not all multi-cellular organisms. In fact, these organisms are the way they are because of the tiny partners they house within and on them. These microbes constitute the microbiome: an “invisible organ” weighing approximately 2.5 to three kilograms in an adult human and much more in larger animals. This…
The interaction between a supermassive black hole in a galaxy named 2MASX J02301709+2836050 and a star orbiting it is seen in this image captured by the Pan-STARRS telescope, in Hawaii, U.S., in an undated handout image provided by NASA. | Photo Credit: Reuters Black holes, celestial objects known for their gluttony, usually eat stars unlucky…

This handout photograph released by the CEA on September 7, 2023, shows a 3D representation of the galaxy “Bubble”, coloured in brown. The image shows the position of the Milky Way, with a small white dot located outside the bubble on the right, in a white cloud. The blue wisps represent the “cosmic web”, the…

Point plotting on Cartesian plane. A coordinate system is a set of numbers that allows you to specify the location of a point in some space. The Cartesian coordinates is one such system, which uses a set of three numbers to specify the distance of a point from three perpendicular planes. In general, this system…
