The forecast for Mars? Otherworldly weather predictions
Thursday, 02 September 2021 09:51
As scientists prepare for crewed research missions to nearby planets and moons, they've identified a need for something beyond rovers and rockets.
They need accurate weather forecasts. Without them, any trip to the surface may be one dust storm away from disaster.
A new Yale study helps lay the foundation for more accurate, otherworldly forecasts by taking a phenomenon related to Ear The case of the missing mantle

In the early solar system, terrestrial planets like Mercury, Venus, Earth and Mars are thought to have formed from planetesimals, small early planets. These early planets grew over time, through collisions and mergers, to make them the size they are today.
The material released from these violent collisions is commonly thought to have escaped and orbited around the sun, bombarding the grow Astronomer recruiting volunteers in effort to quadruple number of known active asteroids
Thursday, 02 September 2021 09:51
The study of active asteroids is a relatively new field of solar system science, focusing on objects that have asteroid-like orbits but look more like comets, with visual characteristics such as tails.
Because finding an active asteroid is such a rare event, fewer than 30 of these solar system bodies have been found since 1949, so there is still much for scientists to learn about them. Rou Chemical clues to the death of massive stars
Thursday, 02 September 2021 09:51
The Universe has countless stars, which come in different masses. The most common ones are the low-mass stars, including our Sun. Massive stars refer to those whose mass is more than eight times the mass of the Sun. The life of low-mass stars is quite long. For instance, our Sun can live for 10 billion years. However, massive stars can only live up to tens of millions of years.
Some of the Astronomers find new clue that heavy stars don't go supernova
Thursday, 02 September 2021 09:51
Conventional theory states that light stars like our Sun gently blow off their layers when they die, while heavy stars explode as a supernova. But for some reason, we are so far failing to find supernovae from stars heavier than eighteen solar masses. Now a team led by SRON astronomers finds a new clue that fuels this apparent mystery.

The rese What can a young star teach us about the birth of our solar system
Thursday, 02 September 2021 09:51
The familiar star at the center of our solar system has had billions of years to mature and ultimately provide life-giving energy to us here on Earth. But a very long time ago, our sun was just a growing baby star. What did the sun look like when it was so young? That's long been a mystery that, if solved, could teach us about the formation of our solar system-so-named because sol is the Latin w Anchoring single atoms

There is a dictum to "never change a running system". New methods can however be far superior to older ones. While to date chemical reactions are mainly accelerated by catalytic materials that comprise several hundreds of atoms, the use of single atoms could provide a new approach for catalysis.

NASA's Deep Space Network looks to the future
Wednesday, 01 September 2021 17:49
When NASA's Mars 2020 Perseverance rover touched down on the Red Planet, the agency's Deep Space Network (DSN) was there, enabling the mission to send and receive the data that helped make the event possible. When OSIRIS-REx took samples of asteroid Bennu this past year, the DSN played a crucial role, not just in sending the command sequence to the probe, but also in transmitting its stunning photos back to Earth.
The network has been the backbone of NASA's deep space communications since 1963, supporting 39 missions regularly, with more than 30 NASA missions in development. The team behind it is now working hard to increase capacity, making a number of improvements to the network that will help advance future space exploration.
