For decades, astronomers have yearned for the day when they could observe the period known as "Cosmic Dawn." This period, which took place roughly 50 million to 1 billion years after the Big Bang, is when the first galaxies in the Universe formed. Observing these galaxies is crucial to understanding cosmic evolution and the forces that govern the Universe (e.g., Dark Matter, Dark Energy, etc.) Thanks to next-generation observatories like the James Webb Space Telescope (JWST), astronomers are starting to get their first look behind the veil.

On July 11, 2022, the James Webb Space Telescope finished its commissioning and commenced science operations. In the three years since, the powerful infrared space telescope has delivered on its promise. It's looked back in time and surprised us with the galaxies it found. It's directly-imaged exoplanets and studied the atmospheres of others. Among this and all of its other science, it's delivered a stream of stunning images.

When it is deployed in 2027, NASA's Nancy Grace Roman Space Telescope will provide new insights into the cosmos. As the successor to the venerable Hubble mission, it will rely on a 2.4 m (7.9 ft) wide primary mirror and a field of view 100 times greater than its predecessor. This next-generation observatory will join the James Webb Space Telescope (JWST), using its high-resolution and high-sensitivity instruments to view objects too faint, cool, or distant for other telescopes to observe. The mission is currently in the System Assembly, Integration and Test, and Launch phase of development at NASA's Goddard Space Flight Center.

A remarkable 2.35 billion year old meteorite found in Africa in 2023 has opened a new window into the Moon's volcanic history, filling a gap in our understanding of how Earth's closest neighbour evolved over billions of years.

In our homes, dust is a nuisance. In space, it's a basic material from which stars, planets, and living things are made. Understanding where cosmic dust comes from is a ground-level question in astronomy, and researchers working with the JWST have uncovered one source: Wolf-Rayet stars.

Astronauts on future missions won't be surviving on freeze-dried meals and protein bars. Instead, they might be harvesting fresh rice from compact plants just 10 centimetres tall, engineered specifically for life beyond Earth. The revolutionary ‘Moon Rice’ project is developing the perfect crop for sustained space habitation, combining cutting edge genetics with the practical needs of deep space exploration.

Venus has always seemed like the last place you'd expect to find life. With surface temperatures hot enough to melt lead and crushing atmospheric pressure, our neighboring planet appears utterly hostile. But high in its clouds, where conditions are surprisingly Earth-like, scientists have discovered something extraordinary: mysterious gases that shouldn't exist, unless something is alive up there….perhaps!

Names are a strange thing in astronomy. Sometimes scientists come up with grandiose, simple name, like the Extremely Large Telescope. Other times, they come up with unique sounding names, like quasars. And sometimes they come up with names that, while descriptive in some sense, are completely misleading in others. That is the case for Little Red Dots (LRD) - active galactic nuclei in the early universe that show up as a little red dot in the images captured by whatever telescope found them. However, they actually represent supermassive black holes hundreds of millions of times the size of our Sun. A new paper from Federica Loiacono and her colleagues at Istituto Nazionale di Astrofisica in Italy describes one of these behemoths they found with the James Webb Space Telescope at a period of the early universe, about 11 billion years ago, known as the “cosmic noon”.

We live in an exciting time of technological innovation and breakthroughs in astronomy, cosmology, and astrophysics. This is similarly true for the Search for Extraterrestrial Intelligence (SETI), which seeks to leverage advances in instrumentation and computing to find evidence of "technosignatures" in the Universe. While the scope has expanded considerably since Cornell Professor Frank Drake and colleagues conducted the first SETI experiment over sixty years ago (Project Ozma), the vast majority have consisted of listening to space for signs of possible radio transmissions.
