Physics

The risk of an asteroid impact has dropped, a private spacecraft is en route to the Moon, and titanium winds were discovered on an exoplanet. This Week in Space.

How long does a second last? Who determined the length of a meter and the weight of a Kilo? How were the units that we use to measure weight and distances determined?

Marking a year since the passing of physicist Arno Allan Penzias, who fled Nazi Germany as a child and co-discovered cosmic background radiation, a breakthrough that solidified the “Big Bang”.

Stephen Hawking, one of the world’s most renowned physicists, revolutionized our understanding of black holes and the universe, all while living with ALS and being confined to a wheelchair.

A spacecraft sets a new record for a Sun flyby, NASA privatizes space communication, a new study reveals the Moon’s age, educational astronomy, and a unique ring. This Week in Space

The charge percentage displayed on our devices’ batteries is a key indicator of their performance. But how is this figure determined?

This year’s Nobel Prizes underscore the transformative impact of the artificial intelligence revolution currently underway, with notable connections to the achievements recognized in physics and chemistry.

Marking 90 years since the birth of Carl Sagan, a trailblazer in planetary science and astrobiology, who became an iconic advocate for science in the media and the public sphere through popular books and a successful TV series.

Marking 135 years since the birth of Edwin Hubble, who revealed that the universe is much larger than the Milky Way, showed that it is steadily expanding, and laid the foundation for the Big Bang theory.

For years, researchers have been puzzled by peculiar findings regarding Uranus’s magnetic field. A new study suggests these findings may have been atypical rather than representative of the planet’s usual characteristics.

Amino acids exist in two mirror-image forms, but only one form serves as the foundation for the building blocks of life. A new study seeks to uncover how this preference emerged.

Mission to Jupiter’s moon launched after a hurricane delay, a European spacecraft will study asteroid deflection, a new Mars sample return mission being developed and researchers investigate why the Moon cooled the COVID-19 pandemic. This Week in Space

The prize will be awarded to two researchers from the USA and Canada for the development of artificial neural networks.

Acclaimed physicist Sergey Gredeskul and his wife Victoria, also a physicist, immigrated to Israel from Ukraine. Sergey was once a leading figure in the theoretical field of disordered systems. Their rich world of knowledge and culture was abruptly cut short when Hamas terrorists brutally murdered them in their home in Ofakim, southern Israel, on the morning of October 7, 2023.

After years of searching, researchers have confirmed the existence of a small planet orbiting Barnard’s Star, one of our closest stellar neighbors.

How can a bomb penetrate a layer of concrete or burrow deep into the ground before detonating? It involves a combination of advanced physics, some chemistry, and quite a bit of technology.

A successful conclusion to the pioneering private mission, promising radiation data from Artemis 1, evidence of water on the Moon, and plans for a lunar communication network. This Week in Space

Radiation measurements from the Artemis 1 mission revealed that the Orion spacecraft provided effective radiation protection, potentially enabling even a mission to Mars. A follow-up article on the Israeli contribution to the experiment is forthcoming.

Standing or sitting? Cyclist body position during sprints could be key to success

The environmental conditions in the sky are responsible for quite a few strange phenomena in planes

If the universe is infinite and filled with shining stars, we might expect a continuously bright sky. Why then is it dark at night?

Could a global nuclear war lead to human extinction? Probably not.

Israeli environmental satellite ends operations, SpaceX back in action, Boeing delayed, and an upcoming nova event.
