Our Sun, like all stars, is made mostly of hydrogen and helium. They are by far the most abundant elements, formed in the early moments of the Universe. But our star is also rich in other elements astronomers call "metals." Carbon, nitrogen, iron, gold, and more. These elements were created through astrophysical processes, such as supernovae and neutron star collisions. The dust of long-dead stars that gathered together into molecular clouds and formed new, younger stars such as the Sun. Stars rich in metals. But there are still stars out there that are not metal rich. These extremely metal-poor stars, or EMPs, hold clues to the origin of stars in the cosmos.

On Monday (April 14), Aisha Bowe became the first Bahamian woman to launch to space — and she already wants to go back.

Heads up aurora chasers! Powerful geomagnetic storm conditions could trigger northern lights at mid-latitudes overnight as CME impact is detected.

Katy Perry isn't the first performer with space ambitions; Lance Bass, Beyonce, Lady Gaga and Justin Bieber all hoped to be first at one time or another.

When JWST launched, it found the most distant known galaxy: JADES-GS-z14-0, with a redshift of 14.32, and seen about 290 million years after the Big Bang. Now, a team of astronomers has gone even deeper, searching for galaxies in the redshift 15-30 range, which would be galaxies from 270 to 100 million years after the beginning of the Universe. They've found a few candidates in the 15-20 range, but these could be closer, low-mass dusty galaxies.

Planetary nebula Kohoutek 4-55 as viewed by the Hubble Space Telescope.

NASA astronaut Don Pettit and two cosmonaut colleagues will return to Earth from the International Space Station on Saturday night (April 19), if all goes to plan.

Oprah Winfrey was on hand April 14 to witness the launch of Blue Origin's historic NS-31 mission, which carried her friend of nearly 50 years, journalist Gayle King, to and from suborbital space.

Alien life could exist on the huge Saturn moon Titan, but probably not in the abundance scientists once hoped, according to a new study.

On 12 March 2025, ESA’s Hera spacecraft soared just 5000 km above Mars and passed within 300 km of its distant moon, Deimos. Captured by Hera’s 1020x1020 pixel Asteroid Framing Camera, this video sequence offers a rare view of the red planet and its enigmatic moon. The original greyscale images have been colour-enhanced based on known surface features.

Cybernetic mercenaries team up to venture into an abandoned colony planet, grab valuable loot, and fight each other in Bungie's Marathon reboot.

Pulsar Fusion just released a video showcasing its planned Sunbird nuclear fusion rocket, which is designed to reach speeds of about 329,000 mph (500,000 kph).

A stunning new image from the James Webb Space Telescope is allowing astronomers to examine the complex and turbulent final stages of a dying star.

It’s no surprise that the future of humanity and even Earth’s biodiversity hangs in the balance and so the race to preserve life on our planet has never been more urgent. Species and ecosystems are vanishing at alarming rate so teams of scientists are turning to cutting-edge solutions to safeguard the natural world for future generations. A new paper explores cryopreservation as one solution, a technology that allows living cells to be frozen and stored for centuries, preserving genetic material and even entire organisms. This approach comes with its own challenges but as we explore this innovative frontier, it becomes clear that reimagining how and where we protect life is essential to securing the planet’s biological legacy.

Jupiter’s moon Europa is a fascinating target for study. Data from the Galileo spacecraft’s Solid State Imager showed that Europa, one of Jupiter’s moons, has a geologically young and varied surface featuring formations like pits, spots, and cryolava domes. A new study has revealed more about the composition of the cryovolcanoes and their domes but also and more excitingly perhaps that they may even provide some form of habitation as we explore the Solar System!

Journalist Gayle King conquered her fear of flying in a big way today (April 14), going to space with Katy Perry and others in Blue Origin's historic all-female flight.

The search for life involves the most sophisticated observational machines known to humanity. They peer out across the light-years, looking for some proof - any proof - that other life exists, out there. What if, despite all our efforts, those observations turn up NO evidence of life elsewhere in our Milky Way Galaxy?

Titan is Saturn's largest moon, with a thick atmosphere and liquid methane lakes, making it the only place besides Earth with stable liquid on its surface. A new paper reveals how a team of researchers have compared real craters on Titan with computer-simulated ones to determine the thickness of its icy shell. This information is important for understanding Titan's interior structure, how it evolved thermally, and its potential to produce organic molecules, making it significant for astrobiological research.

Aisha Bowe filled a milestone seat when she flew on Blue Origin's 11th human and first all-female spaceflight on April 14, 2025.

NGC 1514 is a planetary nebula about 1500 light years away. William Herschel discovered it in 1790, and its discovery made him rethink the nature of nebulae. It's been imaged many times by modern telescopes, and each time a more capable one revisits it, astronomers learn more about it. The JWST is the latest to observe the curious nebula, and its observations help explain the unusual object.

Blue Origin's New Shepard rocket lifted off on the NS-31 mission with Katy Perry and five other women on April 14, for a suborbital spaceflight that left a deep and lasting impact on the entire crew.
