Machine Learning Algorithms Can Find Anomalous Needles in Cosmic Haystacks September 23, 2023
The face of astronomy is changing. Though narrow-field point-and-shoot astronomy still matters (JWST anyone?), large wide-field surveys promise to be the powerhouses of discovery in the coming decades, especially with the advent of machine learning. A recently developed machine learning program, called ASTRONOMALY, scanned nearly four million galaxy images from the Dark Energy Camera Legacy […]

The JWST is Forcing Astronomers to Rethink Early Galaxies September 22, 2023
The JWST has surprised astronomers again. Contrary to our existing understanding, the JWST showed us that the early Universe was full of fully-formed galaxies similar to the ones we see today. The widely-held belief is that the early Universe was too chaotic in its early years, and frequent mergers would’ve disrupted galaxies’ graceful shapes. Galaxy […]

The JWST Just Found Carbon on Europa, Boosting the Moon’s Potential Habitability September 22, 2023
Most planets and moons in the Solar System are clearly dead and totally unsuitable for life. Earth is the only exception. But there are a few worlds where there are intriguing possibilities of life. Chief among them is Jupiter’s moon Europa, and the JWST just discovered carbon there. That makes the moon and its subsurface […]

If You Could See Gravitational Waves, the Universe Would Look Like This September 22, 2023
Our biology limits our vision. Our eyes can only perceive specific wavelengths of light. But what if we could see the Universe in gravitational waves? A new NASA simulation mapped out hundreds of collisions between dense objects, like white dwarfs, neutron stars, and black holes. These collisions happen within galaxies, sending ripples of gravitational waves […]

Solar Sails Could Reach Mars in Just 26 Days September 22, 2023
A recent study submitted to Acta Astronautica explores the potential for using aerographite solar sails for traveling to Mars and interstellar space, which could dramatically reduce both the time and fuel required for such missions. This study comes while ongoing research into the use of solar sails is being conducted by a plethora of organizations […]
