In a three-phase process in which four hydrogen atoms combine to form a helium nucleus, the Sun converts about 600 million metric tons of hydrogen per second to 596 million metric tons of helium. Then that depleted four million metric tons (or 4.26 more precisely) is converted into energy every second. Only 0.00002 percent of…
The James Web Telescope, which is slated to launch in November as a replacement for the Hubble Telescope, is unique in that it’s mainly infrared sensors. While Hubble relies heavily on (and has a small infrared sensor) optical light, this telescope mainly tries to see the universe in high-wavelength infrared. Why is it so popularly…
Hens Stephenson 2-18 is the largest star ever discovered.Hens Stephenson 2-18 has 2,150 times the size of our Sun.It is located in the constellation scutum, 18,900 light-years from Earth.
SpaceX was preparing for a new step. Today we can see it. Booster 4 has stacked 20 of their starship, claiming to be the largest, most powerful, and reusable man-made rights ever. Let’s see an orbital flight sooner rather than later.
Jupiter’s Io is a strange moon with miles of hills and the most active volcanoes in the Solar System. This phenomenon is caused by the gravitational pull of Jupiter and other moons. At the same time, the shadow of this moon falls on Jupiter.
You put some zinc into the hydrochloric acid in a test tube. The formation of hydrogen gas can be seen. That’s the chemistry you know. Zn + HCl → ZnCl2 + H2 In 1766, Henry Cavendish identified this element and named it hydrogen, which means water. The question of whether hydrogen began cooking in the…
For the first time ever, scientists have seen the light from behind a black hole. Black holes are regions in space-time where gravity’s pull is so powerful that not even light can escape its grasp. However, while light cannot escape a black hole, its extreme gravity warps space around it, which allows light to “echo,”…

A mega comet has entered our solar system.Named 2014 UN271, the object will approach the Sun and reach Saturn’s orbit in 2031. It is estimated to be 100 to 370 km wide, and this object is larger than the typical feature of a comet, making it more likely to be a dwarf planet.
In a nutshell, black holes are objects that cannot be penetrated by light due to the force of gravity.For gravity to be so great that even light cannot escape, it is not enough to add the weight or mass of an object, that weight must be confined within a very small range. (Scientifically speaking, weight…
