China has announced that it wants to develop a “space-ground” asteroid early-warning network, while providing few details on what it could look like. But recent papers and presentations to the United Nations provide clues as to what the country has in mind for planetary defense.
The China National Space Administration (CNSA) made the announcement on June 30 — International Asteroid Day —…
The success of NASA’s future moon base depends in large part on mission design, which should allow astronauts to work together well in a way independent from psychological training, a new study asserts.
The goal of the study was to identify “specific conditions” for…
The U.S. Space Force has acquired one of its first publicly acknowledged offensive weapons, one that can blast adversary satellites with beams of electromagnetic radiation to disrupt their signals without physically damaging them.
The system, known as Meadowlands, was…
NASA’s New Horizons probe has woken up in good health nearly 6 billion miles away beyond Pluto after spending nearly a year in hibernation.
Traveling such vast distances between our solar system’s most remote objects means New Horizons often cruises for months at a time with little to do other than passively collect data. During these periods, the probe goes into a hibernation mode in which…
For decades, astronomers have debated whether Earth’s fate was tied to the sun’s. When the star exhausts the hydrogen fuel that powers it about 5 billion years, it will swell into a red giant large enough to engulf Mercury and Venus — and, several studies have…
How do you stop a large, threatening asteroid on its way to Earth? A new Chinese paper, investigating the issue, suggests a “pre-excavation detonation” could be the solution if there’s enough warning time.
There may be millions of asteroids in our solar system, with a…
The world’s first commercially built nuclear-powered satellite has reached orbit aboard a SpaceX Falcon 9 rocket.
The BOHR (Betavoltaic Orbital High-Reliability) satellite, built by Florida-based company City Labs, launched to space early this morning (July 7) on SpaceX’s Transporter-17 rideshare mission.
Transporter-17’s Falcon 9 rocket, which was carrying a total of 81 payloads, lifted…
The mystery of how the sun’s corona, which is its outer atmosphere, reaches millions of degrees could have a surprising explanation: cosmic dust riding the magnetic waves carrying plasma on the solar wind.
“For decades, researchers have focused mainly on how electrons…
PASADENA, California — NASA’s new alien-hunting telescope, the Habitable Worlds Observatory (HWO), will be serviceable out in space (and it will have gamma-ray detectors, to boot).
Do you remember seeing NASA’s space shuttle astronauts working on the Hubble Space…
Astronomers discover radio signals coming from rare 'Blue Eye Pulsar' after decades of silence
July 7, 2026
Silent neutron stars at the center of supernova blast sites may actually be whispering softly, following the detection of faint radio emissions coming from one such object for the first time. The discovery raises the prospect that there could be many more pulsars in our galaxy than we thought.
When a massive star explodes as a supernova, the devastation leads to the star’s core collapsing under…
