NASA's James Webb Space Telescope is poised to reveal some of the earliest galaxies that formed after the Big Bang, the White House said Monday, as anticipation builds for the powerful observatory's first images.

President Joe Biden will unveil the images during a livestreamed event starting at 5:00 pm (2100 GMT).

NASA's Perseverance Mars rover is conducting its science campaign, taking samples at Jezero Crater's ancient river delta, but it's also been busy scouting. The rover is looking for locations where the planned Mars Sample Return (MSR) Campaign can land spacecraft and collect sample tubes Perseverance has filled with rock and sediment.

Lately, the hallways at the Space Telescope Science Institute in Baltimore have been filled with a few more smiles than usual.

Giddy excitement is in the air, anticipating the public release this week of the first significant, full-color images to come from the James Webb Space Telescope, said Susan Mullally, deputy project scientist for the telescope.

Staff at the institute, which operates the revolutionary telescope, have put the finishing touches on the public's first look at the power of Webb to observe what was once unobservable—distant galaxies, the atmospheres of faraway planets.

On Tuesday, the center on Johns Hopkins University's campus will open its doors to a host of scientists, journalists and other eager onlookers to unveil Webb's initial round of observations—ones curated by staffers to showcase the telescope's unique capabilities, with the goal of awing even the most uninspired.

NASA on Friday released a list of the objects captured for Webb's first set of images, including one of the brightest nebulae in the sky, a giant gaseous planet nearly 1,150 light-years from Earth and a quintet of galaxies "locked in a cosmic dance of repeated close encounters.

Coronal mass ejections (CMEs) are eruptive solar events. They are often associated with solar flares and filaments. CMEs can cause space weather events such as geomagnetic storms, high energy electron storms, hot plasma injection, ionospheric storms, and increased density in the upper atmosphere.

Large CME events can impact communications, navigation systems, aviation activities, and even power grids.

US President Joe Biden will Monday release one of the first images taken by the James Webb Space Telescope, the most powerful observatory ever sent into orbit and a leap forward in uncovering the secrets of the distant universe.

The unveiling will take place at 5:00 pm (2100 GMT) during a livestreamed event at the White House, official statements said, leaving the space community in a state of keen anticipation.

NASA revealed last week Webb's first targets included distant galaxies, bright nebulae and a faraway giant gas planet.
