A SpaceX Falcon 9 rocket is lifted off Wednesday night/Thursday morning carrying the first batch of second-generation Starlink satellites to be lofted from the West Coast. Liftoff from Space Launch Complex 4 East at Vandenberg Space Force Base occurred at 9:09 p.m. PDT (1209 a.m. EDT / 0409 UTC July 19).

Record-breaking former NASA astronaut Peggy Whitson appeared on CBS News on July 20 to talk about how the Apollo 11 moon landing influenced her career choice.
The Italian region of Emilia-Romagna was devastated by severe floods in May 2023, claiming lives and displacing thousands of people, resulting in an estimated €8.8 billion in damages. With the region still grappling with the aftermath, satellites have been instrumental in assessing the damages of the affected areas.
The race is on. We are in a Sputnik moment — a sudden and important recognition that we are about to lose the heavens if we do not act with clarity and unity.
The Library of Congress has 400 years of moon maps from around the world. Explore the moon in centuries of maps to celebrate the first-ever human moon landing in 1969.
Harvard astronomer Avi Loeb believes he has found pieces of the first known interstellar meteorite. But others have their doubts, and the debate is turning ugly.

Space-based solar power (SBSP) is considered one of the most promising technologies for addressing Climate Change. The concept calls for satellites in Low Earth Orbit (LEO) to collect power without interruption and beam it to receiving stations on Earth. This technology circumvents the main limiting factor of solar energy, which is how it is subject to the planet’s diurnal cycle and weather. While the prospect of SBSP has been considered promising for decades, it’s only in recent years that it has become practical, thanks to the declining costs of sending payloads to space.
It seems like every week, researchers are finding more and more interesting exoplanets. Many of them have analogs in our own solar system – hot Jupiter or Super Earth are commonly used as descriptions. However, there is a feature of a solar system that doesn’t exist in our solar system but might somewhere out in the galaxy – a Trojan planet. Now researchers from the Centro de Astrobiologia in Madrid and colleagues in the UK, EU, and US have found what they believe to be the first possible evidence of a Trojan planet.
A new super-cool technique could shed light on a hidden dark matter candidate known as 'dark photons.'
Astronomers have spotted the first solid evidence for a planetary Trojan body forming in another system outside our own.
Award-winning sci-fi fantasy author Delilah Dawson turns to the dark side in her new novel "Star Wars: Inquisitor: Rise of the Red Blade."
In radio astronomy, there are lots of natural radio signals to observe. The glow of hydrogen gas, the swirl of electrons along a magnetic field, or the pop-pop-pop of pulsars. These signals usually have a very natural character to them, so astronomers can distinguish them from the artificial chirps and chatters of terrestrial sources. But when you’re looking for the signals of alien civilizations, things can get more tricky. They should have an artificial character similar to the radio signals of humans. So how can astronomers distinguish between the distant artificial signal and the local ones?
Astronomers have observed a 'slow' magnetar releasing bursts of radio waves every 22 minutes. The strange neutron star could change our perception of these extreme stellar corpses.
The James Webb Space Telescope has observed carbon dust in distant and early galaxies in a discovery that could challenge theories regarding the formation of cosmic dust in the infant universe.
Astronomers have found the first evidence of a so-called 'Trojan planet,' in the form of a young Jupiter-like world that's being tailed by a cloud of dust twice as massive as Earth's moon.
Until recently, astronomers could not observe the first stars and galaxies that formed in the Universe. This occurred during what is known as the “Cosmic Dark Ages,” a period that took place between 380,000 and 1 billion years after the Big Bang. Thanks to next-generation instruments like the James Webb Space Telescope (JWST), improved methods and software, and updates to existing observatories, astronomers are finally piercing the veil of this era and getting a look at how the Universe as we know it began.
The National Air and Space Museum debuted the first Barbie dolls to fly in space. They appear to be like all of the other Barbie "Space Discovery" dolls found in stores, and that may be the point.
An unidentified source has been beaming out a pulse of radio waves every 22 minutes since 1988.
For the first time, the NASA/ESA/CSA James Webb Space Telescope has observed the chemical signature of carbon-rich dust grains at redshift ~ 7 [1], which is roughly equivalent to one billion years after the birth of the Universe [2]. Similar observational signatures have been observed in the much more recent Universe, attributed to complex, carbon-based molecules known as polycyclic aromatic hydrocarbons (PAHs). It is not thought likely, however, that PAHs would have developed within the first billion years of cosmic time.
