You may remember in 2023 when I mentioned a five-planet parade in the skies, or in 2024 when six planets aligned

Fun sky news: this week we are in line for a parade of all seven planets!

When and how to view February planet alignment

Skywatchers will get a cosmic treat this week with a celestial gathering of planets.

A planetary alignment, or a “planet parade,” according to the internet, will grace our night sky just after dusk, according to SkyatNightMagazine. You can expect to see seven planets align Friday when Mercury joins Mars, Jupiter, Uranus, Neptune, Venus and Saturn.

Mercury, Venus, Jupiter, and Mars will be visible to the naked eye, but Saturn will be harder to spot low on the horizon, and you’ll need a telescope for Uranus and Neptune. Still, “every other world in our solar system will be visible among the stars at the same time — if you know where to look.”

“You really only have a few minutes after sunset to catch them before they drop below the horizon. After that, you’ll still be able to see Venus, Jupiter, and Mars clearly for a much longer time,” Dr Bloomer added.

I don’t have a telescope, and we often can’t see this kind of event because of city lights. 

Still cool!

Here’s a question: what if we flipped the whole “search for alien life” on its head and asked How Far Away Could We Detect… Ourselves?

A fledgling space-travelling civilization similar to ours may be out there somewhere in the Milky Way. Maybe they have their own fledgling SETI program, complete with radiotelescope arrays scanning the sky for the telltale signs of another technological civilization.

If there is, and if they do, from how far away could they detect our technosignatures? New research is asking that question.

Answer? Very far away!

Better check my work for typos again, because you never know who might see this! 😉

Today is Pluto Day!

Lowell Observatory holds I Heart Pluto Festival

On Feb. 18, 1930, the young astronomer Clyde Tombaugh discovered Pluto, considered for decades a planet and “demoted” to dwarf planet status in 2008.

A few weeks later, an 11-year old girl named Venetia Burney suggested the name Pluto because of its connection to the god of the cold dark underworld.

This in-depth discussion of Pluto covers all sorts of interesting facts, including details of its discovery, how the New Horizons spacecraft gave us a much more detailed picture, and more. (Did you know that Pluto is half the size of the Moon but has five moons of its own? And someone who weighs 180 pounds on Earth would weigh 11 pounds on Pluto.)

What Makes Pluto So Intriguing | TIME

It takes Pluto slightly over 248 Earth years to orbit the sun, which means that on March 23, 2178, one Plutonian year will have elapsed since the dwarf planet was first spotted, on Feb. 18, 1930.

Here’s a cool animation showing our increasingly detailed understanding of Pluto:

And here’s an interactive image of Pluto 3D Model – NASA Solar System Exploration.

You’ll always be a planet to me, Pluto!

Some days you realize that yes, we really are living in the future. Point in case:

Oxford Scientists Say They’ve Achieved Quantum Teleportation

Researchers at the University of Oxford say they’ve achieved quantum teleportation — stitching together separate quantum computers to run an algorithm collaboratively, across a distance, in a “breakthrough” they say could lead to powerful quantum supercomputers.

Still lots to do on the road to practicality, of course, but how cool is that?

Ever wondered what it’s really like to be an astronaut? Do you wish you could ask someone all those burning space questions you’ve got in the back of your mind (and who doesn’t)?

Tomorrow is your lucky day!

Astronauts Are Streaming Live on Twitch—and You Can Talk to Them

This Wednesday evening, you’ll be able to join two astronauts—one of whom is in space right now—on a live stream from space and ask them questions about what it’s like to live and work on the ISS.

You can ask your very own question if you remember to tune in on Wednesday, February 12, at 11:45 a.m. EST (8:45 a.m. PST) on NASA’s Twitch channel.

I’m posting this now to give you time to prepare your best questions and to stock up on snacks like freeze dried ice cream, the weirdly addictive treat I’ve loved since childhood.

For fun, here’s an article on space food, even more on space food, and a sample menu from the International Space Station:

Why do typos matter? Ask the “cried apples”! Also, I am hungry now.

Apparently I’m interested in space food😉 No matter what space stuff you’re into, you’ve got a chance to ask about it tomorrow!

What’s the Difference Between Asteroids, Comets and Meteors? We Asked a NASA Scientist

So, what’s the difference between asteroids, comets, and meteors? Well, asteroids are rocky, comets are icy, and meteors are much smaller and are the shooting stars that you see up in the sky.

What do Saturn, Venus, Neptune, Uranus, Jupiter and Mars all have in common? They’re all currently in alignment, at least from our Earthly perspective.

6 planets aligning in night sky will get even better in February

Venus, Saturn and Neptune will be bunched together low in the southwestern sky, while Mars, Jupiter and Uranus will glow higher in the southern sky.

One trick for finding the planets is to look for how they shine. Stars appear to twinkle while planets do not, making it easier to pick out planets in a star-studded sky.

Weather and light pollution permitting, four of these planets will be visible to the naked eye. Pretty cool!

A NASA astronaut may have just taken the best photo from space—ever

Check out the article for the specific photo, but this is from the same series:

Welcome to the new year! Here’s what you can expect from space in 2025 (including a new way of studying the solar corona that looks enough like the Millennium Falcon to be extra fun):

Look up! Here’s what’s to watch for in space in 2025 – NPR

After a spectacular 2024, which featured a year of wonder in the skies, including a total solar eclipse and rare sightings of the northern lights, 2025 is set to bring even more astronomical events.

I spent a non-zero amount of time today writing out-of-office poetry. Because the holidays need more fun:)
