Exoplanets Transit simulator

This was posted to Mastodon by Dr. Alexandre Santerne. Just had a go and it looks really nice and smooth, and has few options to change the simulation parameters.

Do you know how #astronomers are hunting for #exoplanets ? Most of them are discovered with the transit and/or radial velocity techniques.

We developed at #LAM (#laboratoire d'#astrophysique de #Marseille) a web tool that simulate an #exoplanet and show you their photometric and radial velocity signals. Feel free to play with the parameters and see how they change the signals.

New Science discoveries 1

Something else found on the Fediverse. This was posted by Science Alert. The links should work from here too, if not you will need an account on a Mastodon instance. So lots of interesting things happening

Exoplanets

Another interesting article posted to Fediverse. This is about new exoplanet discoveries. I think this suggests we have found a Jupiter like planet around another star. However this is even further away than the previous planet discovered by Kepler. Another discovery by the Kepler Telescope, which I would guess one day will be observed by the HST, JWST or both.

A really good time to study STEM and get involved in resarch and new discoveries.

Astronomers want a more powerful telescope

This sounds like a really good development, and shows how exciting things are going to get. I have replied and mentioned the Nancy Grace Telescope (due later this decade) and asked about the difference between a space telescope and one placed on the dark side of the moon.

This is another reason to STUDY STEM, and include maths, computing within that so we have people to help analyse all the data being sent back, and we also need people to design, build everything around this.

Mikko Tuomi @mustapipa@scicomm.xyz

Because of the fantastic success of #JWST, now astronomers want even more powerful gear up in space.

They are planning the Habitable Worlds Observatory that would be even bigger and make detecting life on other #Earth-like #planets reality.

The telescope will also be perched at L2. Unlike JWST, it will be designed for robotic servicing and upgrades, which could enable it to operate for decades.

15,000-year-old viruses discovered in Tibetan glacier ice

Another interesting article from Science Daily [1] [2]

Summary:
    Scientists who study glacier ice have found viruses nearly 15,000 years old in two ice samples taken from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any viruses that have been cataloged to date.

So if life can exist in these extreme environments on Earth, could life also exist on other planets, moons in the solar system or Exoplanets and or Exomoons around other stars that have similar conditions.

“These are viruses that would have thrived in extreme environments,” said Matthew Sullivan, co-author of the study, professor of microbiology at Ohio State and director of Ohio State’s Center of Microbiome Science

So while the question of life out side of Earth is not the subject of this paper it does, for me at least, prompts the question could those conditions support life (even viruses) under any frozen surfaces.

I have created a discourse discussion for this [3]. The article is under Biology.

There is also a link here and on discourse to an explanation of 'habitable zone' means. [4] so this states “neither too hot nor too cold”

Earth-like biospheres on other planets may be rare

This is an interesting article on Science Daily. Seems that the conditions on Earth could be far rarer than we think. [1] So we are looking for Earth Like atmospheres, the JWST will really help push this research forward.

Please feel free to discuss further on discourse [2]l. I have also included a link to a infographc, on atmosphere composition in our own solar system [3]

Comment and questions on this.

I just wondered what the range of conditions could support life, for example is there a minimum and corresponding percentage range for Oxygen for example. The same would go for other gasses for example Nitrogen, $CO_2$ etc. Hopefully we can learn more about what is needed for life, so we perhaps increase our chances of finding possible habitable words. This, of course is assuming all life requires Oxygen We have found life in or near volcanoes on Earth, conditions are very hot, and inhospitable to humans generally, not to mention the Sulfur Dioxide and other toxic gasses.

I will try and look in to this further.
