The James Webb Space Telescope just celebrated its second birthday, having started service on July 12, 2022. Here are Webb's 10 best photos so far to mark the occasion.

AI images and deepfakes can be detected by borrowing a technique from astronomy.

NASA released an incredible new look at the Pillars of Creation, showing the celestial phenomenon in an entirely new way.

The James Webb Space Telescope (JWST) has been busy peering into the distant reaches of the Universe, otherwise known as the "Cosmic Dawn." This period when the Universe was only a few hundred million years old is a treasure trove of information about how galaxies evolved when the Universe was very young.

An amateur Italian astronomer discovered five dwarf galaxies, and they are now named after him.

Nearly 10 months after its first successful test photos and six months after its first actual images, the European Space Agency (ESA) has finally released the first full-color science photos from its Euclid space telescope. The wait was worth it.

An international team of astronomers using the James Webb Space Telescope (JWST) detected the most distant black hole merger ever observed.

After more than two decades and a few delays, the Legacy Survey of Space and Time (LSST) Camera is finally built and ready to be sent to the Rubin Observatory in Chile, where it will capture 3,200-megapixel photos of deep space and help scientists unravel the mysteries of the Universe.

My Exmouth eclipse expedition could be a case study on the 'sunk cost fallacy' or proof that even blind persistence can pay off. Either way, it is a saga.

In 1181, a supernova explosion appeared in the night sky for 185 days. Historical records show that the supernova, which some witnesses said looked like a "temporary star," shined as bright as Saturn in the constellation Cassiopeia.

Astronomers using the groundbreaking Event Horizon Telescope (EHT) have captured the first view of the magnetic fields surrounding the supermassive black hole at the center of the Milky Way galaxy, Sagittarius A* (Sgr A*). The novel new image was captured using polarized light.

Using the remarkable 570-megapixel Dark Energy Camera (DECam), astronomers have made a 1.3-gigapixel image of the ghostly Vela Supernova Remnant. The beautiful, detailed, and colorful image is the largest DECam image ever at 35,786 by 35,881 pixels, putting even the highest-resolution medium-format interchangeable lens cameras to shame.

As scientists continue to use the James Webb Space Telescope (JWST) to do incredible things, like find the first direct evidence of a neutron star in a nearby supernova remnant, it also generates many beautiful images that are easy for anyone to appreciate. That's where the monthly Webb Picture of the Month comes in. This month's new photo is of the barred spiral galaxy NGC 1559.

The Sun has been very active so far this month, with powerful sympathetic solar flares dazzling scientists and viewers alike and recent X-class flares making many wonder about communications network integrity. NASA's Solar Dynamics Observatory (SDO) constantly monitors the Sun and captures the recent powerful solar flares in exquisite detail across multiple wavelengths.

Scientists using the James Webb Space Telescope (JWST) have made a monumental discovery, finding evidence for a neutron star at the heart of a young supernova remnant.

Scientists are calling on astrophotographers to capture a comet's broken tail and keep the Earth safe from the Sun.

Unistellar is bringing its Smart Solar Filter to the Odyssey line of telescopes with plenty of time to spare ahead of the highly anticipated solar eclipse hits North America this spring.

The Hubble Space Telescope (HST) has done it again, delivering a spectacular image of the cosmos that is a veritable smorgasbord of color and detail.

The Hubble Space Telescope (HST) upended beliefs about the fundamental nature of the Universe, delivering evidence that the Universe was not slowing down, as gravity seemingly implied it must be, but expanding. 25 years later, the James Webb Space Telescope (JWST) can help scientists make another breakthrough.

The spiral galaxy UGC 3912 doesn't look like much of a spiral in a new image captured by the Hubble Space Telescope. Its unusual and distorted shape is due to a gravitational encounter with a separate galaxy.

Not to be outdone by the James Webb Space Telescope and its beautiful new nebula image, the Hubble Space Telescope delivered a pair of fresh new space photos this week.

The James Webb Space Telescope set its sights on a region of ionized interstellar atomic hydrogen in the Large Magellanic Cloud (LMC) this week, delivering one of Webb's most colorful photos yet.
