Evidence of persistent water vapor discovered on Europa

Evidence of persistent water vapor discovered on Europa

Our solar system has a lot of interesting planets and moons. One of the most interesting objects in the solar system is a moon orbiting the gas giant Jupiter, called Europa. Previously, the Hubble Space Telescope found water vapor in the atmosphere of one of Jupiter's moons called Ganymede. Now Hubble has discovered persistent water vapor in the atmosphere of another moon orbiting Jupiter, this time Europa.

China’s FAST radio telescope captures over 1600 FRBs

China’s FAST radio telescope captures over 1600 FRBs

China's Five-hundred-meter Aperture Spherical radio Telescope (FAST) has been used to detect over 1600 independent Fast Radio Burst (FRB) transmissions. Chinese astronomers detected a huge number of signals over 47 days from FRB 121102. In all, Chinese radio astronomers detected 1652 independent bursts over 47 days beginning on August 29, 2019.

Distant galaxy resembles the future of our solar system

Distant galaxy resembles the future of our solar system

Our sun will run out of fuel in the distant future and become a white dwarf after going through a red giant phase. Astronomers at the W.M. Keck Observatory in Hawaii have discovered a distant planetary system that resembles the future fate of our solar system. The star system has a Jupiter-like gas giant that orbits at a distance from its star similar to Jupiter.

Astronomers discovered a distant galaxy using gravitational lensing

Astronomers discovered a distant galaxy using gravitational lensing

Scientists utilize a technique called gravitational lensing to study galaxies and other celestial bodies that are too far away to observe directly. Gravitational lensing occurs when the light produced by a distant galaxy is magnified by intense gravity from another galaxy directly in front of it. Gravitational lensing produces multiple, stretched, and brightened images of the background galaxy.

Scientists gain new insight into the atmosphere of Pluto

Scientists gain new insight into the atmosphere of Pluto

In the middle of August 2018, the dwarf planet Pluto passed in front of the star giving astronomers an ideal opportunity to learn more about the atmospheric density of the former planet. Researchers from the Southwest Research Institute and a team of astronomers used telescopes at numerous sites in the US and Mexico to observe the atmosphere of Pluto as it was backlit by a well-placed star on the night of August 15, 2018.

LIGO will get new mirror coatings to expand its reach

LIGO will get new mirror coatings to expand its reach

The National Science Foundation funds LIGO observatories, and currently, they are working on applying updates to allow the observatories to reach further into the cosmos. Currently, there are LIGO observatories in Hanford, Washington, and Livingston, Louisiana. In 2015, the observatories detected gravitational waves produced as a pair of black holes collided.

A gigantic comet was originally mistaken for a dwarf planet

Astronomers believe they may have discovered the largest comet in history. The massive comet is called Bernardinelli-Bernstein after its discoverers. It's so massive that when initially discovered, astronomers mistook it for a dwarf planet.

Astronomers discover six early galaxies that have run out of fuel

Astronomers discover six early galaxies that have run out of fuel

Scientists consider early galaxies to be those formed within 3 billion years after the Big Bang. They believe the galaxies would contain large amounts of cold hydrogen gas, which is the fuel used for creating stars. However, scientists studying early massive galleries using the Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered six mysterious galaxies that are very different from what they expected to find in the early universe.

Details of the Tycho moon crater revealed by new radar tech

Details of the Tycho moon crater revealed by new radar tech

New high-resolution image of the moon focusing on the Tycho Crater has been released. It was made using the National Science Foundations Green Bank Observatory and the National Radio Astronomy Observatory. The image of Tycho Crater has a resolution close to five meters by five meters and is comprised of about 1.4 billion pixels.

Amateur astronomer captures Jupiter impact

Amateur astronomer captures Jupiter impact

An amateur astronomer from Brazil named José Luis Pereira enjoys taking photographs and videos of the planets in the solar system on clear nights. Pereira says that when Jupiter, Saturn, and Mars are in opposition, he takes images on every clear night. He particularly enjoys imaging Jupiter, which he calls his favorite planet.

Astronomers predict Supernova Requiem will reappear in 2037

Astronomers predict Supernova Requiem will reappear in 2037

In the study of astronomy, it's difficult to predict many things that occur in the heavens. We can predict things like annual meteor showers and eclipses, but predicting other astronomical occurrences, such as supernovas, is something astronomers are frequently unable to do. For example, astronomers may know when certain stars appear to be preparing to explode into a supernova, but it's difficult or impossible to know exactly when that might happen.

California wildfires threaten SETI radio telescope array

California wildfires threaten SETI radio telescope array

This summer has been a terrible wildfire season around the United States. Perhaps the hardest-hit state of all has been California, where drought and extremely dry conditions along with high winds have stoked wildfires that have destroyed homes and businesses all around the state. SETI Institute is well known for using a radio telescope array to search the galaxy for extraterrestrial life.
