Images and spectra from the James Webb Space Telescope suggest that the first galaxies in the universe are too many or too bright compared to what astronomers expected.

Evidence is building that the first galaxies formed earlier than expected, astronomers announced at the 241st meeting of the American Astronomical Society in Seattle, Washington.

As the James Webb Space Telescope views swaths of sky spotted with distant galaxies, multiple teams have found that the earliest stellar metropolises are more mature and more numerous than expected. The results may end up changing what we know about how the first galaxies formed.

After more than a decade of observations, Northwestern University astrophysicist Jason Wang has constructed an amazing time-lapse video of four planets larger than Jupiter as they revolve around their star, giving viewers a one-of-a-kind glimpse into planetary motion.

Wang, assistant professor of physics and astronomy at Weinberg College of Arts and Sciences, pointed out that it can be difficult to detect planets in a rotating orbit, which is why this video of planetary motion is so striking.

Objects in our solar system, like Jupiter and Mars, are barely visible since we are in the same system and don’t have a top-down view, Wang explains in a statement. Planetary events occur too promptly or slowly, making it hard to capture video of planetary motion of this caliber.

An instrument on the James Webb Space Telescope suffered an interruption on January 15, and the likely culprit was a cosmic ray.

NASA and the Canadian Space Agency suspect that a cosmic ray strike is to blame for an anomaly on the James Webb Space Telescope.

A planet called Wolf 1,069 b has been found 31 light years away from Earth which has the same mass as our planet and is in the “habitable zone” due to its temperature Astronomers have found a similar sized planet to Earth which could be habitable due to the temperature and atmosphere.

About the mission, Canada’s role, asteroid Bennu, mission timeline, and news.

Astronomers discovered a world beyond our solar system, a exoplanet, that is around the size of Earth and could possibly harbor conditions that might allow life to thrive. It’s called Wolf 1,069 b.

Astronomers have measured the mass of a lone white dwarf star for the first time. This type of smoldering stellar remnant is formed at the end of the lives of low-mass stars and will be what the sun leaves behind when it dies in around 5 billion years.

The Hubble Space Telescope measured the mass of a white dwarf designated LAWD 37, which burned out over 1 billion years ago. In the work, scientists used a phenomenon first predicted in 1915 by Albert Einstein called “gravitational lensing,” which involves the bending of light by objects of great mass. The team determined that LAWD 37 has a mass around 56% that of the sun. The finding confirms current theories of how these stellar remnants form and evolve. This particular white dwarf is well studied because it is relatively close to Earth at just 15 light-years away in the constellation of Musca.
