We know that regular supernovae pose no existential threat to life on Earth in the near-term. But there are other varieties of supernova that are a little bit harder to predict, and little bit harder to spot.

Dark Energy is a mystery so daunting that it stretches and strains our most robust theories. The Universe is expanding, driven by the unknown force that we've named Dark Energy. Dark Energy is also accelerating the rate of expansion. If scientists could figure out why, it would open up a whole new avenue of understanding.

The ESA's Euclid Space Telescope has already wowed us with some fantastic images. After launching in July 2023, the telescope delivered some stunning first images of the Perseus Cluster, the Horsehead Nebula, and other astronomical objects. Now, the telescope has released its first images of its three Deep Fields.

The James Webb Space Telescope (JWST) has achieved groundbreaking discoveries in the field of exoplanet studies. In particular, it has made strides in the analysis of their atmospheres by studying light from the parent star as it travels through the gas surrounding the planets. JWST has recently bucked the trend and observed a some gas giant planets in the system HR 8799 and detected the presence of carbon dioxide in their atmospheres, suggesting there are similarities between the formation of this system and our own.

With luck and clear skies, you can spot Venus crossing between the Earth and the Sun this weekend.Up for a challenge? If skies are clear, you may be able to complete a rare feat of visual athletics this coming weekend, and follow Venus on its trek from the evening and into the morning sky.

On 19 March 2025, the European Space Agency’s Euclid mission released its first batch of survey data, including a preview of its deep fields. Here, hundreds of thousands of galaxies in different shapes and sizes take centre stage and show a glimpse of their large-scale organisation in the cosmic web.

After an unexpectedly long mission in orbit, astronauts Suni Williams and Butch Wilmore finally arrived home. Their SpaceX Dragon capsule detached from the International Space Station early Tuesday morning, beginning the de-orbiting process. Nick Hague and Aleksandr Gorbunov are also on board and, following a nail biting descent, finally at 7.58pm EDT today.

The most dangerous parts of a supernova explosion are the outputs like X-rays and gamma rays. Even though they only share a small fraction of a supernova’s power, they are extremely dangerous.

The Square Kilometre Array (SKA) remains under construction with completion still a few years away. However, engineers recently provided an exciting preview having installed 1,024 of the planned 131,072 antennas and capturing a test image of the sky. The image covers about 25 square degrees and reveals 85 of the brightest known galaxies in the region. Once fully operational, the complete array is expected to detect more than 600,000 galaxies within this same area!

More than one million asteroids larger than 1 km exist in the main asteroid belt (MAB) between Mars and Jupiter. Their roots are in a much smaller number of larger asteroids that broke apart because of collisions, and the MAB is populated with debris fields from these collisions. Researchers have created a geological map of the MAB by tracking meteorites that fell to Earth and determining which of these debris fields they originated in.

Update March 18, 6:30 p.m. EDT: Dragon Freedom splashed down off the coast of Tallahassee, Florida, and the spacecraft was brought aboard the recovery vessel, Megan.

Welcome back to our five-part examination of Webb's Cycle 4 General Observations program. In the first and second installments, we examined how some of Webb's 8,500 hours of prime observing time this cycle will be dedicated to exoplanet characterization and the study of galaxies that existed at "Cosmic Dawn" - ca. less than 1 billion years after the Big Bang.

We see the Universe through a glass darkly, or more accurately, through a dusty window. Interstellar dust is scattered throughout the Milky Way, which limits our view depending on where we look. In some directions, the effects of dust are small, but in other regions the view is so dusty it's called the Zone of Avoidance. Dust biases our view of the heavens, but fortunately a new study has created a detailed map of cosmic dust so we can better account for it.

When massive stars explode as supernovae, they can leave behind neutron stars. Other than black holes, these are the densest objects we know of. However, their masses are difficult to determine. New research is making headway.

The search for life has become one of the holy grails of science. With the increasing number of exoplanet discoveries, astronomers are hunting for a chemical that can only be present in the atmosphere of a planet with life! A new paper suggests that methyl halides, which contain one carbon and three hydrogen atoms, may just do the trick. Here on Earth they are produced by bacteria, algae, fungi and some plants but not by any abiotic processes (non biological.) There is a hitch, detecting these chemicals is beyond the reach of current telescopes.

The China Space Station Telescope, scheduled for a 2027 launch, will offer astronomers a fresh view on the cosmos. Though somewhat smaller than Hubble, it features a much wider field of view, giving a wide-field surveys that will map gravitational lensing, galaxy clusters, and cosmic voids. Scientists anticipate it will measure dark energy with 1% precision, differentiate between cold and dark matter models, and evaluate gravitational theories.

SpaceX launched a batch of 23 Starlink V2 Mini satellites to low Earth orbit as it and NASA are in the process of returning four people from the International Space Station back to Earth.

The journey of Firefly Aerospace’s Blue Ghost lunar lander came to an end over the weekend. The 14-day operation on the surface of the Moon was officially declared over on Sunday, March 16, when the robotic lander sent its final transmissions back to Earth.

From far enough away, most supernovas are benign. But the thing you have to watch out for are the X-rays.

When water is sprayed or splashed, different size microdroplets develop opposite charges. This "microlightning" could've provided the energy needed to synthesize prebiotic molecules necessary for life.
