LOOK EAST AT SUNSET: When the sun goes down tonight, step outside, face East, and look up. Jupiter and the Moon are having a bright conjunction in the constellation Gemini. It's a beautiful way to end the day: sky map.
A METEOR STORM OVER MISSOURI? No, it's just SpaceX. Only one of these streaks in the night sky over Albany, Missouri, is a natural meteor:
"Shown here is a lonely bright meteor passing through the atmosphere on Feb. 23rd," says photographer Dan Bush. "Also seen are dozens of satellites whose paths crisscrossed the night sky during the ~10 minute integration time. Two or three lines along the horizon just above the trees are planes."
The majority of these streaks are Starlink satellites. At a conference in 2020, Elon Musk famously said "I am confident that we will not cause any (interference) in astronomical discoveries. Zero. We'll take corrective action if it's above zero." It might be time to start.
In only two days since Bush took this photo, SpaceX has launched 54 more Starlinks, bringing the 2026 total to 512. Altogether, there are now 9,833 Starlinks swarming our planet. Here's what that looks like.
With no end in sight for SpaceX launches, the "meteor storm" will continue for the foreseeable future. Submit your satellite interference photos here.

18K GOLD "ALWAYS AND FOREVER" PENDANT: Are you looking for an unforgettable gift? Consider the Always and Forever Space Pendent. On Aug. 29, 2023, the students of Earth to Sky Calculus launched it to the stratosphere onboard a cosmic ray research balloon:
You can have it for $229.95. Engraved with the words "I love you always and forever", this 18K gold-plated sterling silver pendant has a heart-shaped ruby crystal in the middle surrounded by a ring of glittering 5A cubic zirconia nuggets. It is a visually striking premium pendant that makes a once-in-a-lifetime anniversary or birthday gift.
The students are selling space pendants to pay the helium bill for their cosmic ray ballooning program. Each one comes with a greeting card showing the jewelry in flight and telling the story of its trip to the stratosphere and back again.

Every night, a network
of NASA
all-sky cameras scans the skies above the United
States for meteoritic fireballs. Automated software
maintained by NASA's Meteoroid Environment Office
calculates their orbits, velocity, penetration depth
in Earth's atmosphere and many other characteristics.
Daily results are presented here on Spaceweather.com.
On Feb. 23 2026, the network reported 5 fireballs.
(5 sporadics)
In this diagram of the inner solar system, all of the fireball orbits intersect at a single point--Earth. The orbits are color-coded by velocity, from slow (red) to fast (blue).

Potentially Hazardous Asteroids ( PHAs)
are space rocks larger than approximately 100m that
can come closer to Earth than 0.05 AU. None of the
known PHAs is on a collision course with our planet,
although astronomers are finding new
ones all the time.
On February 26, 2026 there were 2349 potentially hazardous asteroids.

Cosmic Rays in the Atmosphere |
SPACE WEATHER BALLOON DATA: Almost once a week, Spaceweather.com and the students of Earth to Sky Calculus fly space weather balloons to the stratosphere over California. These balloons are equipped with sensors that detect secondary cosmic rays, a form of radiation from space that can penetrate all the way down to Earth's surface. Our monitoring program has been underway without interruption for 10 years, resulting in a unique dataset of in situ atmospheric measurements.
Latest results (Nov. 2024): Atmospheric radiation is sharply decreasing in 2024. Our latest measurements in November registered a 10-year low:
What's going on? Ironically, the radiation drop is caused by increasing solar activity. Solar Cycle 25 has roared to life faster than forecasters expected. The sun's strengthening and increasingly tangled magnetic field repels cosmic rays from deep space. In addition, solar coronal mass ejections (CMEs) sweep aside cosmic rays, causing sharp reductions called "Forbush Decreases." The two effects blend together to bring daily radiation levels down.
.Who cares? Cosmic rays are a surprisingly "down to Earth" form of space weather. They can alter the chemistry of the atmosphere, trigger lightning, and penetrate commercial airplanes. According to a study from the Harvard T.H. Chan school of public health, crews of aircraft have higher rates of cancer than the general population. The researchers listed cosmic rays, irregular sleep habits, and chemical contaminants as leading risk factors. A number of controversial studies (#1, #2, #3, #4) go even further, linking cosmic rays with cardiac arrhythmias and sudden cardiac death.
Technical notes: The radiation sensors onboard our helium balloons detect X-rays and gamma-rays in the energy range 10 keV to 20 MeV. These energies span the range of medical X-ray machines and airport security scanners.
Data points in the graph labeled "Stratospheric Radiation" correspond to the peak of the Regener-Pfotzer maximum, which lies about 67,000 feet above central California. When cosmic rays crash into Earth's atmosphere, they produce a spray of secondary particles that is most intense at the entrance to the stratosphere. Physicists Eric Regener and Georg Pfotzer discovered the maximum using balloons in the 1930s and it is what we are measuring today.
