Finally, an Explanation for the Cold Spot in the Cosmic Microwave Background

According to our current Cosmological models, the Universe began with a Big Bang roughly 13.8 billion years ago. During the earliest periods, the Universe was permeated by an opaque cloud of hot plasma, preventing atoms from forming. About 380,000 years later, the Universe cooled to a temperature of about -270 °C (-454 °F), which converted …

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 …

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 …

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 …
