EVSN - Lightweight Mars-sized Planet Found in TESS Data
The 365 Days of Astronomy
From December 3, 2021. A Mars-sized planet was found just 31 light-years away, orbiting its star every eight hours and having 55 percent the mass of the Earth, leading scientists to conclude it’s mostly made of an iron-nickel core. Plus, water on Earth, a huge comet, and a review of a Canon lens. We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

Guide to Space - It Came From Deep Space!
The 365 Days of Astronomy
From Oct 17, 2017. Some comets orbit the Sun on a regular basis, but others come in from deep space, a region known as the Oort Cloud. What causes them to make this journey, and will we ever be able to explore the Oort Cloud? Team: Fraser Cain - @fcain / [email protected] Karla Thompson - @karlaii / .

Travelers in the Night Eps. 797 & 798: Recoveries & Destination Enceladus

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. From May 2024. Today's 2 topics: - It is essential that asteroid hunters keep track of potentially dangerous asteroids to make sure that their orbits haven’t changed as they encounter other objects in space to make them a threat to our home planet. - Life on Earth appears to have formed in our oceans. Scientists are thus on the hunt for other worlds which have oceans of liquid water and thus potentially could be the home...

info_outlineFrom May 19, 2025.
In this week’s closer look we are going to look at the earth-facing missions that are getting dragged down by our atmosphere and will be forcibly retired by physics in the next few years, again with no replacements in the works. These missions allow us to do long term monitoring of our planet, its atmosphere, and the variables that help us understand everything from weather to climate change. We also look at cool new exoplanet discoveries, the beautiful death of a star, and tales from the launch pad.
