How to Find Credible Sources

Look for college and university websites:

They usually have publications and online educational material that anyone can access. Look for material written by academics that are knowledgeable in their subject area and find material that is peer reviewed if possible, such as journal papers. 

Look at government websites representing government agencies (such as Statistics Canada):

You can either go directly to the websites and search for the information there, or you can use a search engine to find the information. For example, if you want to find articles on turbines from the NASA website you would enter this into Google: “site:http://www.nasa.gov turbines”. This would find turbine related webpages on the NASA website. The general format here is: “site:(website URL) (search term)”.

Search for PDF documents:

You can search for these by entering this into Google: “filetype:pdf (search term)”. But again, check the authors and see who they work for. It’s generally better to have authors who don’t have a conflict of interest, such as those who work for private companies.

The children should learn to develop the sounds from the external objects and from the way their own feelings are related to them. Everything should be derived from the feeling for language. In the word “roll” the child should really feel: r,o,l,l. It is the same thing for every word.

It is terrible to see how a single unclear idea, a single formula without meaning, lurking in a young man’s head, will sometimes act like an obstruction in an artery, hindering the nutrition of the brain, and condemning its victim to pine away in the fullness of his intellectual vigor and in the midst of intellectual plenty.

The Search for Starless Planets

While it’s familiar to us, our solar system may actually be a bit of an oddball. Our Milky Way galaxy is home to gigantic worlds with teeny-tiny orbits and planets that circle pairs of stars. We’ve even found planets that don’t orbit stars at all! Instead, they drift through the galaxy completely alone (unless they have a moon to keep them company). These lonely island worlds are called rogue planets.

image

Where do rogue planets come from?

The planet-building process can be pretty messy. Dust and gas around a star clump together to form larger and larger objects, like using a piece of play-dough to pick up other pieces.

Sometimes collisions and close encounters can fling a planet clear out of the gravitational grip of its parent star. Rogue planets may also form out in space on their own, like the way stars grow.

image

Seeing the invisible

We’ve discovered more than 4,000 exoplanets, but only a handful are rogue planets. That’s because they’re superhard to find! Rogue planets are almost completely invisible to us because they don’t shine like stars and space is inky black. It’s like looking for a black cat in a dark room without a flashlight.

Some planet-finding methods involve watching to see how orbiting planets affect their host star, but that doesn’t work for rogue planets because they’re off by themselves. Rogue planets are usually pretty cold too, so infrared telescopes can’t use their heat vision to spot them either.

So how can we find them? Astronomers use a cool cosmic quirk to detect them by their effect on starlight. When a rogue planet lines up with a more distant star from our vantage point, the planet bends and magnifies light from the star. This phenomenon, called microlensing, looks something like this:

image

Imagine you have a trampoline, a golf ball, and an invisible bowling ball. If you put the bowling ball on the trampoline, you could see how it made a dent in the fabric even if you couldn’t see the ball directly. And if you rolled the golf ball near it, it would change the golf ball’s path.

image

A rogue planet affects space the way the bowling ball warps the trampoline. When light from a distant star passes by a rogue planet, it curves around the invisible world (like how it curves around the star in the animation above). If astronomers on Earth were watching the star, they’d notice it briefly brighten. The shape and duration of this brightness spike lets them know a planet is there, even though they can’t see it.

image

Telescopes on the ground have to look through Earth’s turbulent atmosphere to search for rogue planets. But when our Nancy Grace Roman Space Telescope launches in the mid-2020s, it will give us a much better view of distant stars and rogue planets because it will be located way above Earth’s atmosphere — even higher than the Moon!

Other space telescopes would have to be really lucky to spot these one-in-a-million microlensing signals. But Roman will watch huge patches of the sky for months to catch these fleeting events.

image

Lessons from cosmic castaways

Scientists have come up with different models to explain how different planetary systems form and change over time, but we still don’t know which ones are right. The models make different predictions about rogue planets, so studying these isolated worlds can help us figure out which models work best.

When Roman spots little microlensing starlight blips, astronomers will be able to get a pretty good idea of the mass of the object that caused the signal from how long the blip lasts. Scientists expect the mission to detect hundreds of rogue planets that are as small as rocky Mars — about half the size of Earth — up to ones as big as gas giants, like Jupiter and Saturn.

image

By design, Roman is only going to search a small slice of the Milky Way for rogue planets. Scientists have come up with clever ways to use Roman’s future data to estimate how many rogue planets there are in the whole galaxy. This information will help us better understand whether our solar system is pretty normal or a bit of an oddball compared to the rest of our galaxy.

image

Roman will have such a wide field of view that it will be like going from looking at the cosmos through a peephole to looking through a floor-to-ceiling window. The mission will help us learn about all kinds of other cool things in addition to rogue planets, like dark energy and dark matter, that will help us understand much more about our place in space.

(assuming you're talking about the slang experiment) any particularly amusing incidents you'd like to share?

Remy yelling "yes girl" as I "vibe checked" Roman. This unintentionally started a "vibe check war" between certain members of the household. It was quite an evening

Satellite imagery reveals new penguin colonies in Antarctica
"Birds in these sites are therefore probably the 'canaries in the coalmine' -- we need to watch these sites carefully as climate change will affect this region."

Satellite imaging has revealed that there are nearly 20% more emperor penguin colonies in Antarctica than previously thought.

However, while the discovery has been welcomed, the previously undiscovered animals will act as “canaries in the coalmine” when it comes to studying the impact of global warming, experts have said.

Scientists discovered 11 new colonies, meaning there are now 61 colonies across the continent overall.

The study, which used satellite mapping technology, will “provide an important benchmark for monitoring the impact of environmental change on the population of this iconic bird,” researchers said.

Am I so difficult to understand and so easy to misunderstand in all my intentions, plans, and friendships? Ah, we lonely ones and free spirits—it is borne home to us that in some way or other we constantly appear different from what we think. Whereas we wish for nothing more than truth and straightforwardness, we are surrounded by a net of misunderstanding, and despite our most ardent wishes we cannot help our actions being smothered in a cloud of false opinion, attempted compromises, semi-concessions, charitable silence, and erroneous interpretations. Such things gather a weight of melancholy on our brow; for we hate more than death the thought that pretence should be necessary, and such incessant chafing against these things makes us volcanic and menacing. From time to time we avenge ourselves for all our enforced concealment and compulsory self-restraint. We emerge from our cells with terrible faces, our words and deeds are then explosions, and it is not beyond the verge of possibility that we perish through ourselves. Thus dangerously do I live! It is precisely we solitary ones that require love and companions in whose presence we may be open and simple, and the eternal struggle of silence and dissimulation can cease.
