SAN FRANCISCO — Weather data company ClimaCell announced plans Feb. 24 to launch dozens of radar satellites.
“We are building the first of its kind proprietary satellites equipped with radar, and launching them into space to improve weather monitoring and forecasting capabilities,” Shimon Elkabetz, ClimaCell CEO and co-founder, said in a statement.
How were the Trojan asteroids discovered and named?

On Feb. 22, 1906, German astrophotographer Max Wolf helped reshape our understanding of the solar system. Again.
Born in 1863, Wolf had a habit of dramatically altering the astronomy landscape. Something of a prodigy, he discovered his first comet at only 21 years old. Then in 1890, he boldly declared that he planned to use wide-field photography in his quest to discover new asteroids, which would make him the first to do so. Two years later, Wolf had found 18 new asteroids. He later became the first person to use the "stereo comparator," a View-Master-like device that showed two photographs of the sky at once so that moving asteroids appeared to pop out from the starry background.

Does this image make you anxious or are you already tracking where all the wires go? If the latter, you might have what it takes to be an astronaut!
It is an exciting time for space. With NASA's latest rover safely on Mars and ESA's call for the next class of astronauts, the space industry is teeming with possibilities.
This image taken in ESA's Columbus laboratory on the International Space Station is a snapshot of the many opportunities in space research and exploration.
In the center is the Biolab facility, a fridge-sized unit that hosts biological experiments on micro-organisms, cells, tissue cultures, small plants and small invertebrates. Performing life science experiments in space identifies the role that weightlessness plays at all levels of an organism, from the effects on a single cell up to a complex organism—including humans.
The facility has enabled researchers to make some remarkable discoveries, most notably that mammalian immune cells required a mere 42 seconds to adapt to weightlessness, prompting more questions but also an overall positive outlook for long-duration human spaceflight.
The pink glow in the image is from the greenhouse that has enabled many studies on plant growth in space.

The Israel Missile Defense Organization (IMDO), in the Directorate of Defense Research and Development of the Israel Ministry of Defense, and the U.S. Missile Defense Agency (MDA) have begun the development of the Arrow 4 interceptor. Arrow 4 will be the next generation of endo-exoatmospheric interceptors for the Arrow Weapon System, which today consists of Arrow 2 and Arrow 3 interceptors.

A team of scientists has detected the presence of a high-energy neutrino - a particularly elusive particle - in the wake of a star's destruction as it is consumed by a black hole. This discovery, reported in the journal Nature Astronomy, sheds new light on the origins of Ultrahigh Energy Cosmic Rays - the highest energy particles in the Universe.

Astrophysicists have traced a subatomic particle called a neutrino to its cosmic origins, a tidal disruption event located some 700 million light-years from Earth.
The new research - published Monday in the journal Nature Astronomy - suggests the violent destruction of a faraway star by a supermassive black hole was powerful enough to send a tiny, near-frictionless particle racing acr Binary stars are all around us, new map of solar neighborhood shows
