Astrophysicist Hakeem Oluseyi believes there are nine realms of the universe that make our existence possible. Discover more about what he calls "the dark realm," and other exciting news in space science: buff.ly/6SuZQnT

"I do a calculation in my book of how many worlds should exist in our galaxy with large life forms like ourselves. And it’s like one out of a million star systems... So this universe is hostile to life throughout the majority of its volume, yet here we are." —Dr. Hakeem Oluyesi

w/ Oli Shorttle, @johannateske.bsky.social & Eliza Kempton we reviewed our current understanding and prospects for peaking on the inside of small #exoplanets in "Constraining exoplanet interiors using observations of their atmospheres": www.science.org/stoken/autho... & arxiv.org/abs/2510.08844 🔭🧪⚒️☄️

Illustration of predicted interior structures of sub-Neptune exoplanets. Observed density and atmospheric constraints are interpreted in three scenarios, each with a gaseous envelope. Water worlds have a small metal core, rocky mantle, high-pressure ice layer, and possible liquid water ocean. Gas dwarfs have a larger metal core and a magma ocean. Global supercritical regimes have no clear boundaries between layers. Image credit: Mark A. Garlick.

In 2024, the Sun reached the peak of its 11-year solar cycle. Over the year, the Sun produced hundreds of notable solar flares and coronal mass ejections! ☀️

I have uploaded a 13-minute YouTube video presenting the highlights of those events! Enjoy. youtu.be/WJxuxAA82uI?...

Titan as seen through three different filters: August 20, 2013 - From Val Klavans (valklavans.bsky.social) - https://flic.kr/p/fAMQzR

On August 20, 2013, Cassini's camera system, the Imaging Science Subsystem (ISS), looked for clouds across Titan's sub-Saturn hemisphere from 1.33 million kilometers (0.82 million miles) away. The ISS took a number of images of Titan in different filters. Three of which were used for this composite image. This RGB false color composite of Titan is in 3 different filters: continuum filter (where methane is more transparent), methane band (where methane is strongly absorbing), and ultraviolet.

These images were taken on August 20, 2013 and received on Earth August 22, 2013. The images were taken using the CL1, CB3, UV3 and MT3 filters.

China's Tianwen-2 is on its way to Kamoʻoalewa, an asteroid that currently doubles as a "quasi-moon" of Earth. The spacecraft will collect samples & bring them back home.

On its outward trajectory, Tianwen-2 looked back and got this lovely view of our planet. 🧪🔭

english.news.cn/20251001/ef3...

This image released by the China National Space Administration (CNSA) on Oct. 1, 2025 shows a view of the Tianwen-2 probe alongside Earth, captured by the probe during its deep-space journey. The newly released image, acquired by a monitoring camera mounted on the probe's robotic arm, showcases China's five-starred red flag and the white return capsule against the backdrop of a distant, blue Earth. (Some slight image processing by me.)
