NASA’s Webb’s Mid-Infrared Instrument is prepared to perform science

2,583 Comments / James Webb Space Telescope, NASA /

The James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) has concluded its post-launch preparations and is now prepared to do science. The last MIRI mode to be approved was its coronographic imaging capability, which uses two different designs of masks to block off light from a star to make observations of the star’s orbiting planets. These […]

Magnetars are one of the most interesting objects in space. These neutron stars are so massive that one teaspoon of what they are made of would weigh nearly one billion tons and possess magnetic fields that are a hundred million times more powerful than any magnet on Earth. Despite these facts, researchers don’t know much

NASA’s Webb Near-Infrared Imager and Slitless Spectrograph Instrument prepared to see the universe using over 2000 different infrared colors

467 Comments / James Webb Space Telescope, NASA /

One of NASA’s Webb’s four main scientific instruments, specifically the Near-Infrared Imager and Slitless Spectrograph instrument (NIRISS) is now ready to perform science. According to NASA, the last mode of the NIRISS to be completed before the instrument was confirmed ready to start its scientific operations was the Single Object Slitless Spectroscopy (SOSS) capability. The

James Webb Space Telescope will help uncover more of the early universe

131 Comments / Galaxies, James Webb Space Telescope, NASA /

Before the James Webb Space Telescope, space telescopes have looked back at lights from galaxies that reached a period of no earlier than 400 million years after the big bang. One question that remains unsolved and important even today is what were the first galaxies like when the universe was experiencing a time phase known

Researchers recognize a possible clue for Pluto’s moon Charon’s red cap

173 Comments / Solar system /

Southwest Research Institute scientists mixed data based on NASA’s New Horizons mission along with novel lab experiments and exospheric modeling to reveal the likely composition of the red cap on Pluto’s moon Charon and how it might’ve formed. This primary description of Charon’s dynamic methane atmosphere based on recent experimental data provides a spectacular brief

NASA’s Webb’s Mid-Infrared Spectroscopy will reveal Elements and Molecules

163 Comments / James Webb Space Telescope, NASA /

This week NASA’s James Webb Space Telescope team continues to operate through Webb’s 17 science instrument modes. Webb team checked off numbers 5 ( NIRCam grism time series) and 4(imaging time series), both of which will be used to study exoplanets and other time-variable sources. Number 12 which is the NIRISS aperture masking infertometry mode,

Astronomers learn and discovers how galaxies form through galactic mergers

1 Comment / cosmic collisions, Galaxies /

In the United Kingdom (UK), astronomers announce that they find how galaxies such as the Milky Way formed over more than 10 billion years through multiple varieties of galaxies colliding together. Galaxies are the largest single islands in the universe in which their origin of how they form or evolve is a very old question
