Astronomers were recently amazed to find an aurora-like display some 40,000 kilometers above a sunspot. Researchers from the New Jersey Institute of Technology's Center for Solar-Terrestrial Research (NJIT-CSTR) detailed radio observations of the event that share characteristics with the auroral radio emissions...

The sky over North, Central, and South America will feature a celestial delight later today, as an annular solar eclipse creates a "ring of fire." An annular solar eclipse differs from a total eclipse in that the moon is at the farthest point in its orbital path from Earth, keeping it from being able to completely...

Last year, NASA's Parker Solar Probe flew through one of the most powerful coronal mass ejections (CMEs) ever recorded. The spacecraft's excursion through the CME gave scientists a new perspective on a 20-year-old theory about the interaction of CMEs with interplanetary dust, which could aid in future space weather...

NASA's Parker Solar Probe and the European Space Agency's (ESA) Solar Orbiter performed incredibly hot spacecraft gymnastics to help solve a cosmic mystery about the Sun. The Sun's atmosphere, known as its corona, has a temperature of around one million degrees Celsius, while its surface is only about 6000 degrees...

An international collaboration of scientists has discovered the highest-energy light ever observed from the sun. These gamma rays also much brighter than scientists previously thought.
Humankind has been trying to figure out the bright orb in the sky since the beginning of time. In more recent years, scientists...

A duo of coronal mass ejections (CMEs) is projected to combine into one "cannibal" CME before impacting Earth later today. The combo could potentially cause a very strong geomagnetic storm here on Earth.
NASA describes a CME as a magnetically generated solar phenomenon that can hurl billions of tons of solar...

The aurora borealis, typically only seen by those in far north locations like Alaska, Canada, and Scandinavia, is projected to be viewable in up to 17 US states, including New York and others along the East Coast on July 13, 2023.
The aurora borealis, better known as the Northern Lights, enamor and amaze everyone...

NASA's Solar Dynamic Observatory (SDO) captured a stunning image of an X1.0 solar flare. The event took place on July 2, 2023, and caused a temporary degradation or complete loss of High-Frequency radio signals in some parts of the world.
NASA has been studying how the Sun creates solar activity and drives space...

A new study concerning data collected by NASA's Parker Solar Probe (PSP) says that understanding how and where solar wind originates will aid in predicting solar storms that could potentially have devastating effects on satellites, the electrical grid, and communication networks such as the internet. The team of...

A team of astronomers has detected a brown dwarf with a scorching daytime temperature of 8,000 Kelvin (13,940 degrees Fahrenheit). This means this extremely hot object is hotter than our very own Sun, which has temps averaging around 5,500 Kelvin, or approximately 9,400 degrees Fahrenheit.
Object WD0032-317B was...

An international team of astronomers has discovered the second-ever multiplanetary circumbinary system, giving Star Wars fans more hope that one day they might be able to travel to a Tatooine-like planet. The newly found planet, BEBOP-1c, joins TOI-1338b, which was discovered in the same system in 2020.

A pair of supermassive black holes, known as a binary black hole system, emitted a flare that is brighter than a trillion stars. The duo is located in galaxy OJ287 and are so close together they appear as one dot in the night sky.
Galaxy OJ287 lies in the direction of the constellation Cancer at approximately 5...

The world's most powerful ground-based solar telescope captured new close-up images of the Sun that are scorching hot. The National Science Foundation's (NSF) Daniel K. Inouye Solar Telescope's images highlight an assortment of sunspots and peaceful regions of the Sun.
A mosaic of eight images was released...

An international team of researchers used AI to identify relationships between solar wind measurements from heliophysics missions and geomagnetic perturbations observed at ground stations across the globe. The result was a computer model called DAGGER (Deep Learning Geomagnetic Perturbation), which can predict...

Astronomers have documented an aging star engulfing a planet for the first time ever. The new study is a possible foreshadowing of what will eventually happen to our own planet as the Sun goes through the same end-of-life-transition.
As our own Sun gets closer to its red giant phase in approximately 6 billion...

Astronomers have discovered the closest-known black hole to Earth, at just 1600 light-years away. It is also the first clear detection of a dormant stellar-mass black hole in the Milky Way.
Stellar-mass black holes typically weigh in at approximately five to 100 times the mass of our Sun. These types of black holes...
