5,000 Exoplanets!
Before NASA’s TESS (Transiting Exoplanet Survey Satellite) mission launched in 2018, astronomers tried to understand what it would find in advance. One study calculated that TESS would find between 4430 and 4660 new exoplanets during its primary two-year-long mission. The primary mission (PM) is over, and TESS is in its extended mission (EM) now. The …

Incredible Image Shows Twin Stellar Jets Blasting Out of a Star-Forming Region
Young stars go through a lot as they’re being born. They sometimes emit jets of ionized gas called MHOs—Molecular Hydrogen emission-line Objects. New images of two of these MHOs, also called stellar jets, show how complex they can be and what a hard time astronomers have as they try to understand them. Stellar jets from …

Webb Has Arrived Successfully at L2
It’s really happening. The James Webb Space Telescope has successfully reached its orbital destination in space, 1.5 million km (1 million miles) from Earth. A final 5-minute thruster firing on January 24, 2022 put JWST in its halo orbit at the Sun-Earth Lagrange 2 (L2) point. The formal commissioning process can now begin. “We’re excited …

A Private Mission to Scan the Cloud Tops of Venus for Evidence of Life
The search for life on Venus has a fascinating history. Carl Sagan famously and sarcastically said there were obviously dinosaurs there since a thick haze we couldn’t see through covered the surface. More recently, evidence has pointed to a more nuanced idea of how life might exist on our sister planet. A recent announcement of …

13 Rovers Recently Competed to Scour the (Simulated) Moon to Harvest Resources
Challenges are one way to encourage innovation. They’ve been leveraged by numerous space and non-space research organizations in the last decade, with varying degrees of success. The European Space Agency (ESA) is now getting in on the action, with a challenge to prospect the moon for vital resources that will make a sustainable presence there …

It’s Been Constantly Raining Meteors on Mars for 600 Million Years. Earth too.
New research shows that Mars has faced a constant rain of meteors during the last 600 million years. This finding contradicts previous research showing that the impact rate has varied, with prominent activity spikes. Why would anyone care how often meteors rained down on Mars, a planet that’s been dead for billions of years? Because …

ESA’s ARIEL Mission Will Study the Atmospheres of More Than 1,000 Exoplanets
We found our first exoplanets orbiting a pulsar in 1992. Since then, we’ve discovered many thousands more. Those were the first steps in identifying other worlds that could harbour life. Now planetary scientists want to take the next step: studying exoplanet atmospheres. The ESA’s ARIEL mission will be a powerful tool. ARIEL stands for Atmospheric …
