There was a total solar eclipse in the UK back in 1999. I travelled down to Cornwall, a loooooong 8 hour car drive and quite typically for UK, it was cloud. For me, I either need to wait until 2090 when I will be the ripe old age of 117 or travel abroad. Even if I had seen it, I would have been able to enjoy the spectacle for just over 2 minutes! Imagine though, experiencing a total solar eclipse that lasts 48 minutes instead of the usual four minutes or so that we see on Earth. A UK led space mission plans to make this possible by creating artificial solar eclipses in space, revolutionising how we study our nearest star and potentially saving decades of waiting for natural eclipses.

Protoplanetary disks made of gas and dust form around young stars, and this is where planets from. These disks don't last forever. Eventually, the star's energetic output dissipates the disk through photoevaporation, the material gets taken up in planets, and the planet-forming process ceases.

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.
