James Webb Telescope captures its first images of an exoplanet
Exoplanets are rarely seen in images.
In a first for the James Webb Telescope, astronomers from the joint NASA/ESA/CSA cooperative used the space-based telescope to bring back images of an exoplanet. Exoplanets are planets orbiting other suns than our own, helping us to understand if we are unique in the universe or if other Earth-like planets exist.

The images of the exoplanet are seen through four different light filters. They show a gas giant, a planet with no rocky surface that could not be habitable. The light filters show how the infrared telescope’s gaze is easily capturing images of planets out beyond our solar system. These images lead the way toward future observations that can reveal a broad range of information never before seen on exoplanets.
E-2D Advanced Hawkeye
The aircraft is one of Northrop Grumman’s best models.
The Northrop Grumman E-2 Hawkeye is an American all-weather, carrier-capable tactical airborne early warning aircraft. Its latest and most advanced version is the E-2D Advanced Hawkeye.
which features the AN/APY-9 radar (capable of detecting fighter-sized stealth aircraft), radio suite, mission computer, integrated satellite communications, flight management system, improved T56-A-427A engines, a glass cockpit and aerial refueling.
The E-2D Advanced Hawkeye provides warfighters with the necessary situational awareness to compress the time between initial awareness and active engagement.

Astronomers discover seven new pulsars
Using the Large Phased Array (LPA) radio telescope of Pushchino Radio Astronomy Observatory (PRAO) in Russia, astronomers have detected seven new pulsars and determined their basic parameters. The finding is reported in a paper published August 18 on the arXiv pre-print repository.
Pulsars are highly magnetized, rotating neutron stars emitting a beam of electromagnetic radiation. They are usually detected in the form of short bursts of radio emission; however, some of them are also observed via optical, X-ray and gamma-ray telescopes.
Now, a group of Russian astronomers led by PRAO’s Sergey Tyul’bashev reports the detection of seven new pulsars. The discovery was made with LPA as part of a daily sky survey conducted in a test mode, covering a full day in right ascension and 50 degrees in declination. The new pulsars were detected at a frequency of 111 MHz.
