Guide To Space - Can There Be Life On Planets Around Red Dwarf Stars?

mercredi 1 octobre 2025 • Durée 10:46

https://www.youtube.com/watch?v=NkPhmtJRvsM

From Jan 24, 2019.

As astronomers find more and more planets around other stars, the big question we want to know is: are they habitable, could there be life there?

The vast majority of stars in the Milky Way are red dwarf stars, and most of the planets in habitable zones have been found orbiting these cooler, less massive stars. What are the chances that life could get going on these worlds?

Space Stories - Parallax: Measuring the Cosmos

mardi 30 septembre 2025 • Durée 09:48

Hosted by Richard Drumm, our Editor.

The word of the day today is parallax! Specifically stellar parallax.

So what’s parallax & what does it mean to astronomers? As it happens, I was part of the UVA Parallax team in the early 1980s. Best part-time job ever! So for once I might know a little bit about what I’m talking about! I’ll do my best to describe it so you can understand the science.

An easy method to help grasp the concept is for you to hold out your thumb at arm’s length and close one eye, then the other, switching back & forth between them while looking at your thumb. The location of your thumb seems to shift with each eye’s view. If your, uh, thumb was 20 feet away from your eye, the shift would be much less. You can measure the baseline, the distance between your eyes and, using a little trigonometry calculate the distance to your thumb. Simple!

Travelers in the Night Eps. 333E & 334E: Worth Tracking & Backwards

dimanche 21 septembre 2025 • Durée 06:05

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

From April 2025.

Today's 2 topics:

- Greg Leonard was observing with our team's 60 inch telescope on Mt. Lemmon in Arizona when he discovered a relatively large space rock, 2017 FD157, which can theoretically come closer to the Earth's surface than the communications satellites!

- Dr. Paul Wiegert of Western University in Canada, led a team of astronomers who have determined that 2015 BZ509, a 2 mile diameter object, bucks the solar system traffic by traveling in a direction backwards to all of the planets!

Astronomy Cast Ep. 760: What to Look For This Summer

lundi 23 juin 2025 • Durée 29:30

https://www.youtube.com/watch?v=9hG8Q3ZSX50

Hosted by: Fraser Cain and Dr. Pamela L. Gay

Streamed live on Jun 16, 2025.

It’s almost time for our annual summer hiatus, but before we go, we wanted to direct you towards all the fun and space stuff we’ll be enjoying this summer. We’ve got meteor showers, planets, rocket launches, TV shows, movies! Here’s what’s good.

In a couple of weeks, we'll go on hiatus, but we want to make sure you are ready for stuff we can anticipate happening.

Travelers in the Night Eps. 321 & 322: Dangerous Comet & Dust Stories

dimanche 22 juin 2025 • Durée 06:05

From September 2024.

Today's 2 topics:

- Protection against a comet strike is worth considering. Every year, if we are lucky, several comets can come close enough for the Sun to warm and us to see the beautiful changing dust and gas clouds around them with binoculars or our unaided eyes. So far asteroids have gotten most of the attention as dangerous celestial neighbors, however, Dr. Joseph Nuth, a researcher at NASA's Goddard Space Flight Center in Greenbelt, Maryland recently pointed out "Comets can also deliver a heaping helping of calamity to Earth, and scientists and policymakers alike should start taking measures to combat the threat".

- Collect your own beautiful micro-meteorite sample.

It is estimated that several hundred thousand pounds of left over particles from the formation of our solar system enters the Earth's atmosphere every day with perhaps 10% of the of the total reaching the surface of our home planet. The individual grains of cosmic dust or micro-meteorites as they are also called range in size from the diameter of a human hair to twice the thickness of a dime.

EVSN - Black Hole Caught Eating Faster Than Normal

vendredi 20 juin 2025 • Durée 23:01

From June 28, 2022.

With a little bit of luck and a lot of time on different telescopes, researchers managed to capture the black hole in the center of the Milky Way, SgrA*, consuming matter at a faster rate than usual. Plus, Australia launches a rocket, a couple of Mars stories, and strange glaciers on Earth.

Cheap Astronomy - Dear CA #119: Out There!

mercredi 18 juin 2025 • Durée 14:57

Space travel or the lack thereof.

Hosted by Steve Nerlich.

Dear Cheap Astronomy – Interstellar trade

As regular listeners are aware, here at Cheap Astronomy, we think faster than light travel just ain’t going to happen. That limits your trade options a good deal if our potential alien trading partners are anywhere up to a hundred light years or more away.

Dear Cheap Astronomy – Why aren’t we doing more with artificial gravity

Good question. As we’ve discussed on this podcast and as others have discussed on pretty much every space-related podcast there is, zero gravity – OK, microgravity – is really bad for you. Your bones dissolve, your muscles wither, your cardiovascular system is deconditioned, your eye geometry changes and if that’s not bad enough your face gets all puffy too.
