Mariner was the first spacecraft to be launched to study Mercury on November 3, 1973Launched by NASA, this robotic spacecraft was the first spacecraft to fly over multiple planets. What is a fly-by or gravity assist? This is a technique used to increase the speed of an exploration vehicle when it is sent into space….

Usain Bolt on asteroids

October 26, 2021

Discovered the fastest asteroid in the Solar System.The Chilean Dark Energy Camera (DECam) has detected another asteroid, AJ193, which orbits at 94,000 kilometers per hour and completes its orbit in just 113 days, just days after it crossed Earth. The runner was first spotted by scientists on August 13. Named 2021 PH27, the asteroid orbits…

What is the reason for this magical sight in the sky (northern lights / Aurora) ???

October 23, 2021

Northern lights (aurora) are phenomena that appear from the first night of the night 18 ° to 23 away from the Earth’s magnetic poles. It is usually found in green and red. Charged particles from the solar wind are attracted by the Earth’s magnetic field. Aurora is formed when these particles collide with gaseous molecules…

Planets outside the Milky Way

As of February 1, 2020, 3900 extraterrestrials have been confirmed in 2894 planetary families. But all of these planets revolve around stars in our parent galaxy, the Milky Way. In May 2018, astronomers at…

Umbra, Penumbra and Antumbra

October 9, 2021

The light emitted by a light source, like any other opaque object, casts shadows from the moon and earth into space. Each shadow has 3 different regions: amber, penumbra, and antumbra.Umbrella / amber is the dark core of the shadow. Imagine a light source and an object casting a shadow. If you are standing under…

Why does glass transmit light?

October 3, 2021

Photons pass through the material because they do not have the energy needed to excite a glass of electrons to a higher energy level. Physicists sometimes talk about this based on the band theory that energy levels coexist in areas known as energy bands. There are areas between these bands called band gaps, where the…

Light or electromagnetic radiation.

October 3, 2021

The maximum speed at which we can communicate information in this universe is the speed of light, which is 3 million km / second. That is, nothing moves faster than this. For example, suppose the sun suddenly disappears in a second, and it takes about 8 minutes and 20 seconds for the earth to see…

CUTE in search of secrets of planets hotter than the sun

September 29, 2021

The Colorado Ultra Violet Transit Experiment (CUTE) Cube Satellite launches to learn more about planets that are warmer than the Sun. Cute will collect information on the hottest planet ever discovered, including KELT-9b. The Atlas V rocket was launched from California on September 27 with Lantasat. Kevin France, a researcher at the Laboratory for Atmospheric…
