The solar arrays have successfully deployed on Northrop Grumman’s Cygnus cargo spacecraft that is on its way to deliver more than 8,200 pounds of scientific investigations, cargo, and supplies to the International Space Station after launching at 8:31 p.m. EDT Sunday from NASA’s Wallops Flight Facility on the Eastern Shore of Virginia.
The James Webb Space Telescope has used its infrared sensors to show us El Gordo’s gravitationally distorted galaxies, a red giant star and tons of other space goodies Hubble could only hint at.
After the tragic implosion of the Titan submersible. OceanGate’s co-founder is all prepped up for another venture. The co-founder of OceanGate, Guillermo Söhnlein has grand aspirations for future. By 2050, he would like to see 1,000 humans living in the clouds of Venus.
journey breaks several laws of physics in order to reach the known limit of the universe, using a spacecraft capable of travelling at any speed.
distance and speed are approximate, giving us an idea of how fast the spacecraft has to travel to move through the vast expanses of the universe.
the way, an AI will explain some important elements of the journey, to give us a more complete picture of what we are seeing.

Earth’s oldest craters could give scientists critical information about the structure of the early Earth and the composition of bodies in the solar system as well as help to interpret crater records on other planets. But geologists can’t find them, and they might never be able to, according to a new study published in the Journal of Geophysical Research: Planets.
Geologists have found evidence of impacts, such as ejecta (material flung far away from the impact), melted rocks, and high-pressure minerals from more than 3.5 billion years ago. But the actual craters from so long ago have remained elusive. The planet’s oldest known impact structures, which is what scientists call these massive craters, are only about 2 billion years old. We’re missing two and a half billion years of mega-craters.
The steady tick of time and the relentless process of erosion are responsible for the gap, according to Matthew S. Huber, a planetary scientist at the University of the Western Cape in South Africa who studies impact structures and led the new study.
Einstein predicted the existence of these crosses back in 1915. Now, they are used to study distant galaxies.
Researchers revisit a neglected decay mode with implications for fundamental physics and for dating some of the oldest rocks on Earth and in the Solar System.
With a half-life of 1.25 billion years, potassium-40 does not decay often, but its decays have a big impact. As a relatively common isotope (0.012% of all potassium) of a very common metal (2.4% by mass of Earth’s crust), potassium-40 is one of the primary sources of radioactivity we encounter in daily life. Its decays are the primary source of argon-40, which makes up almost 1% of the atmosphere, and the copious amount of heat released from these decays threw off early estimates of the age of Earth made by Lord Kelvin. Potassium-40 is largely responsible for the meager radioactivity in our food (such as bananas), and it is a significant source of noise in some highly sensitive particle physics detectors. This isotope and its decay products are also useful tools in dating rocks and geological processes that go back to the earliest parts of Earth history. And yet some long-standing uncertainty surrounds these well-studied decays.
Astronomers used the Hubble Space Telescope to determine that a nearby exoplanet is losing its atmosphere due to interactions with its star.
Webb is casting the universe in a new light, but the space telescope’s discovery of a cosmological question mark has us scratching our heads.
As the James Webb Space Telescope enters its second year of capturing images of the depths of space, it has already revealed a treasure trove of beauty from around the universe, both near and far from home.
The James Webb Space Telescope (JWST) was launched on Christmas Day in 2021, and sent back its first batch of images on July 12, 2022, making this July its functional birthday.
This telescope, now situated around 1 million miles from Earth as it photographs the cosmos, is the successor space telescope to Hubble, designed to peer far back into the universe’s history and study the earliest stars and galaxies.
