Solar coronal jets are fast moving plumes of plasma that erupt suddenly from the polar regions of the Sun. Astronomers believe that these help heat up the solar corona, but the physics behind the formation of these jets is poorly understood. Recently a team of astronomers have used observations with the Solar Dynamic Observatory and the Solar Orbiter to discover that multiple intertwining magnetic fields that connect and reconnect can power these fast moving jets.

NASA’s Exoplanet Watch Wants Your Help Studying Planets Around Other Stars
It’s no secret that the study of extrasolar planets has exploded since the turn of the century. Whereas astronomers knew less than a dozen exoplanets twenty years ago, thousands of candidates are available for study today. In fact, as of January 13th, 2023, a total of 5,241 planets have been confirmed in 3,916 star systems, with another 9,169 candidates awaiting confirmation. While opportunities for exoplanet research have grown exponentially, so too has the arduous task of sorting through the massive amounts of data involved.
Astronomers Spot an Orphaned Protostar
Astronomers have performed an impressive suite of observations at multiple wavelengths of the same system, dubbed the HH 24 complex. This complex hosts stars in the process of being born and the impacts of their violent interactions with each other, including the ejection of one of their siblings.

How Life Reshapes the Habitable Zone
Astronomers are very interested in the Habitable Zone of distant stars, which is the orbital radius where liquid water, and therefore potentially life, can exist on a planet in that region. But life itself changes the characteristics of a planet. New research suggestions that life is even capable of redefining what the Habitable Zone can mean.
UFO Update Says Pentagon’s Case Count Is Rising Rapidly
A new report to Congress says the Pentagon’s task force on UFOs — now known as unidentified aerial phenomena, or UAPs — has processed more reports in the past couple of years than it did in the previous 17 years. But that doesn’t mean we’re in the midst an alien invasion.
