Here are the cosmic targets for James Webb’s Telescope’s first images

This week will see the exciting release of the first science images from the James Webb Space Telescope. The telescope, a combined project from NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA), was launched in December last year and since then has arrived at its orbit around the sun, deployed its hardware, and aligned its mirrors and instruments. Now, NASA is gearing up for the release of the first images from the telescope, set for July 12, and has announced which objects the images will show.

The first object is the Carina Nebula, a large cloud of dust and gas where an enormous star exploded in 1843. The nebula is famed for its beauty as well as for hosting star WR 25, the brightest star in our galaxy. It is large by nebulae standards and is located 7,600 light-years away in the constellation Carina, visible in the southern hemisphere.

The second object is a giant exoplanet called WASP-96b. Located 1,150 light-years away, it is around half the mass of Jupiter and it orbits very close to its star, with a year there lasting just 3.4 days. The data on this planet will include a spectrum, which can be used to tell what an object is composed of. It will likely include data about the exoplanet’s atmosphere, which is one of Webb’s new capabilities.

The third object is another nebula, the Southern Ring Nebula, which is bright and a distinctive round shape, made up of gas around a star coming to the end of its life.

The fourth and fifth objects are on a larger scale, including a galaxy group called Stephan’s Quintet located 290 million light-years away which has four of its five galaxies in very close proximity, and a deep field image called SMACS 0723 in which gravitational lensing gives a deep view of extremely distant and faint galaxies.

These images are just a taster of the work that James Webb will do in its first year, and show the variety of types of objects that it can study. The images are scheduled to be released on Tuesday, July 12, beginning at 10:30 a.m. ET (7:30 a.m. PT), and you can watch the release via a live broadcast on NASA TV.

If you're looking for a relaxing way to peruse the fascinating sights of space on your lunch break, then a newly updated tool from NASA has you covered. The Space Telescope Live tools show the current targets of the James Webb Space Telescope and the Hubble Space Telescope, letting you browse the cosmos from the perspective of two of the hardest-working telescopes out there.

You can visit the web-based tools at WebbTelescope for the James Webb Space Telescope and HubbleSite for the Hubble Space Telescope. Clicking on a link will bring you to a portal showing the current and past observations of the telescope and a ton of detail about the observations.

This famous supernova remnant is hiding a secret
Webb’s NIRCam (Near-Infrared Camera) captured this detailed image of SN 1987A (Supernova 1987A). At the center, material ejected from the supernova forms a keyhole shape. Just to its left and right are faint crescents newly discovered by Webb. Beyond them an equatorial ring, formed from material ejected tens of thousands of years before the supernova explosion, contains bright hot spots. Exterior to that is diffuse emission and two faint outer rings. In this image blue represents light at 1.5 microns (F150W), cyan 1.64 and 2.0 microns (F164N, F200W), yellow 3.23 microns (F323N), orange 4.05 microns (F405N), and red 4.44 microns (F444W).

When massive stars reach the end of their lives and explode in a supernova, they can leave behind huge structures in space called supernova remnants. These are often favorite targets of astronomers because of their beautiful and distinctive shapes. They include the famous SN 1987A remnant that was imaged by the James Webb Space Telescope last year. Now, astronomers using Webb have peered closer at this remnant and found something special inside.

The SN 1987A supernova was first observed in 1987 (hence its name) and was bright enough to be seen with the naked eye, making it extremely recent by astronomical standards. Stars live for millions or even billions of years, so observing one coming to the end of its life in real time is a real scientific treat. When this star died, it created a kind of supernova called a core collapse, or Type II, in which the heart of the star runs out of fuel, causing it to collapse suddenly and violently. This collapse it so severe that the material rebounds and is thrown out in an explosion traveling up to a quarter of the speed of light.

James Webb photographs two potential exoplanets orbiting white dwarfs

Even though scientists have now discovered more than 5,000 exoplanets, or planets outside our solar system, it's a rare thing that any telescope can take an image of one of these planets. That's because they are so small and dim compared to the stars that they orbit around that it's easier to detect their presence based on their effects on the star rather than them being detected directly.

However, thanks to its exceptional sensitivity, the James Webb Space Telescope was recently able to image two potential exoplanets orbiting around small, cold cores of dead stars called white dwarfs directly.
