Scientists have discovered potentially inhabited worlds not far from Earth

Two American astronomers were able to discover three small rocky planets at once. Scientists were able to discover three small rocky planets at a distance of 100 light years from us. Two of them are very similar to Earth and could potentially be inhabited worlds. A third planet may also have liquid water on its surface. The Conversation writes about it.Category SCIENCE AND IT LIVE … Continue reading Scientists have discovered potentially inhabited worlds not far from Earth

Firefly’s Alpha rocket reaches orbit on second launch

KIHEI, Hawaii — Firefly Aerospace’s Alpha launch vehicle reached orbit on its second launch Oct. 1, more than a year after the vehicle’s first launch failed. The Alpha rocket lifted off from Space Launch Complex 2 at Vandenberg Space Force Base at 3:01 a.m. Eastern. The rocket’s upper stage achieved orbit nearly eight minutes later. After a circularization burn, the upper stage deployed its payloads, … Continue reading Firefly’s Alpha rocket reaches orbit on second launch

Scientists have found out how the dangerous journey of the Earth through the Milky Way affects the planet

New research shows that Earth’s geology is influenced by comets that fall every 200 million years as the planet passes through the spiral arms of our galaxy. Scientists believe that Earth’s journey through the Milky Way may have greatly affected the planet’s geology. Scientists have come to the conclusion that during the passage of the planet through the spiral arms of the Milky Way, every … Continue reading Scientists have found out how the dangerous journey of the Earth through the Milky Way affects the planet

Falling of an asteroid to the Earth – an asteroid that moves faster than the speed of sound flies towards the planet

The celestial body will fly past the planet already on September 6. A small asteroid will fly by the Earth on September 6 at a speed that is 10 times faster than the speed of a bullet. According to The Jerusalem Post, the diameter of the celestial body designated 2022 QC7 is 16-36 meters, according to NASA data. For comparison, 36 meters is about half … Continue reading Falling of an asteroid to the Earth – an asteroid that moves faster than the speed of sound flies towards the planet

The Sun will absorb Mercury, Venus and Earth: how it will happen

Scientists have long estimated that the Sun will explode within the next 5 billion years. A new study says that when this happens, the Sun will destroy Mercury, Venus and Earth. However, it is not entirely clear how such a destruction will occur. To find out, scientists conducted several 3D hydrodynamic simulations. This made it possible to consider possible scenarios of the development of events … Continue reading The Sun will absorb Mercury, Venus and Earth: how it will happen
