Earth will be struck today by a coronal mass ejection from a huge solar flare that erupted from the sun on New Year’s Eve.

The New Year’s Eve flare created a CME, a huge bubble of plasma from a region of the sun called the corona, which is equivalent to the sun’s outer atmosphere, and this has an Earth-directed component. Though this massive ejection of plasma will only graze the magnetic bubble surrounding our planet Tuesday (Jan. 2), the magnetosphere, it could trigger a geomagnetic storm that could affect communications and power infrastructure.

The coronal mass ejection CME was hurled into space by an X-class solar flare that burst from the surface of the sun at 4:55 p.m. EST (2155 GMT) on Sunday (Dec. 31). It is the most powerful flare that has happened on the sun during the current solar cycle, solar cycle 25, which began in Dec. 2019. In fact, the flare that ended 2023 with a bang is the largest that has been observed since Sept. 10, 2017, according to the Space Weather Prediction Center of the National Oceanic And Atmospheric Administration (NOAA).

Matter inside neutron stars can have different forms: a dense liquid of nucleons or a dense liquid of quarks.

Recent studies reveal that in neutron stars, quark liquids are fundamentally different from nucleon liquids, as evidenced by the unique color-magnetic field in their vortices. This finding challenges previous beliefs in quantum chromodynamics and offers new insights into the nature of confinement.

New research reveals a never-before-seen behavior in a repeating Fast Radio Burst, offering fresh insights into these mysterious cosmic phenomena.

Astronomers are continuing to unravel the mystery of deep space signals after discovering a never-before-seen quirk in a newly-detected Fast Radio Burst (FRB).

FRBs are millisecond-long, extremely bright flashes of radio light that generally come from outside our Milky Way galaxy. Most happen only once but some “repeaters” send out follow-up signals, adding to the intrigue surrounding their origin.

Research on an ancient spiral galaxy reveals crucial insights into early galaxy formation, highlighting rapid star formation and unique structural features compared to contemporary galaxies.

A new snapshot of an ancient, far-off galaxy could help scientists understand how it formed and the origins of our own Milky Way.

At more than 12 billion years old, BRI 1335–0417 is the oldest and furthest known spiral galaxy in the Universe.
