Tracking exoplanets via orbital mechanics isn't easy. Plenty of variables could affect how a planet moves around its star, and determining which ones affect any given exoplanet requires a lot of data and a lot of modeling. A recent paper from researchers led by Kaviya Parthasarathy from National Tsing Hua University in Taiwan tries to break through the noise and determine what is causing the Transit Timing Variations (TTVs) of HAT-P-12b, more commonly known as Puli.

Extreme solar storms are a relatively rare event. However, as more and more of our critical infrastructure moves into space, they will begin to have more and more of an impact on our daily lives, rather than just providing an impressive light show at night. So it's best to know what's coming, and a new paper from an international team of researchers led by Kseniia Golubenko and Ilya Usoskin of the University of Oulu in Finalnd found a massive Extreme Solar Particle Event (ESPE) that happened 12350 years ago, which is now considered to be the most energetic on record.

Spacecraft orbiting Mars can reveal small features on the planet's surface, but there are only so many things you can see from above. When a meteor strikes the surface of Mars, it can excavate sub-surface material, allowing scientists to study what lies beneath. Researchers have simulated various impacts on Mars, changing the sub-surface material from bedrock to water-ice glaciers, and then calculated what should be visible after an impact, enabling new science.

Earth's magnetosphere channels particles from solar storms into stunning auroras. Mars lacks a planet-wide magnetic field and has patchy auroras barely detectable with instruments. Or so we thought. New images captured by NASA's Perseverance Rover with its Mastcam-Z instrument show green auroras in visible light. When humans finally walk on Mars and look to the skies, they could possibly see faint auroras there, too.

In a recent paper, an international team proposed an ultra-long wavelength radio interferometer that could examine the Cosmic Dark Ages and Cosmic Dawn. Known as the Dark Ages Explorer (DEX), this telescope could provide fresh insights into how and when the first stars and galaxies formed.

The satellite population in Low-Earth Orbit (LEO) is not an open book. While data on many satellites is public, others are shrouded in secrecy, and information is incomplete for others. New research shows how observers can determine satellite shapes by watching them occult background stars.

When the JWST came to life and began observations, one of its first jobs was to gaze back in time at the early Universe. The Assembly of Galaxies is one of the space telescope's four main science themes, and when it observed the Universe's first galaxies, it uncovered a mystery. According to our understanding of how galaxies evolve, some were far more massive than they should be.

NASA’s Perseverance Rover didn't just look up—it captured a sprint across the Martian sky! On March 1st, its navigation camera locked onto Deimos as the moon raced overhead in the pre-dawn darkness. Sixteen rapid-fire, 3-second exposures stacked together reveal the moon's movement across the Martian sky. The pictures were taken in very low light, so it's pretty grainy and noisy, but there are two additional stars in the sky, Regulus and Algieba, in the constellation Leo.

Scientists have discovered that black holes don't just devour everything—they also fire back. While nothing can escape the event horizon, black holes generate ferocious winds that blast outward at significant fractions of the speed of light. New research challenges the long-held belief that they flow smoothly and continuously. Instead, these winds are violent, fragmented bursts resembling rapid-fire streams of gas bullets. Astronomers have now witnessed this phenomenon firsthand, detecting five distinct gas components travelling 20-30% the speed of light and erupting like geysers from the black hole's vicinity.

Astronomers have discovered a protoplanetary disks where planets are born thrive in the most violent region of our Galaxy. For years the galactic center was thought to be too chaotic and hostile for planet formation. This is wrong. New ALMA observations have seen planet nurseries flourishing in the turbulent Central Molecular Zone near our Galaxy's heart, challenging everything we thought we knew about how worlds are born. Planets find a way.
