Space & Astronomy Classes

Picture a patch of night so narrow that it spans less than one-tenth the apparent width of the full Moon. Hubble revisited that direction in Fornax for nearly two million seconds, and the resulting eXtreme Deep Field contains roughly 5,500

You drop the bottle in the blue bin and walk away feeling finished. You just started a shipment — not a recycling. EPA's definition is industrial, not moral: collect the thing, sort it, process it into a raw material, remanufacture that ma

The Hubble eXtreme Deep Field turns an apparently empty patch of sky into thousands of faint galaxies whose light began its journey at different distances and times, in some cases more than 13 billion years ago, making the image a layered r

Picture yourself approaching Saturn with Cassini: the familiar loops widen until bands, gaps, ripples, and shadows fill your view. You are not seeing a polished hoop but countless separate particles, mostly empty space between them, sharing

You bite a cracker, and saliva turns its surface into a chemical sample. Molecules then reach taste pores; that is where tasting starts.

See how water levels, elevation, sediment, migration space, and living shorelines shape wetland resilience—and why adaptation must keep uncertainty and tradeoffs visible.

Follow carbon through marshes, mangroves, and seagrass—from plant growth and tidal export to buried soil, disturbance, restoration, and honest climate accounting.

Dry the bread, mix three eggs to a cup of milk, and soak until a slim dry spine remains. A first plate tonight, with the science that keeps the center custard.

Learn why space has a cold radiation background but spacecraft, lunar soil, and telescope instruments can reach very different temperatures.

Learn how a star's tiny, repeating wobble revealed 51 Pegasi b and changed the search for planets around Sun-like stars.

Learn how stellar orbits, binary companions, gravitational lensing, and the Event Horizon Telescope turn invisible black holes into measurable objects.

Follow Cassini from its long journey and Huygens' landing on Titan to the 22-orbit Grand Finale, the last signal, and the planetary-protection choice that sent the spacecraft into Saturn.

Follow a meteorite from mineral selection to isotope measurement, and learn how scientists separate a date from the story it tells.

Follow the pressure, oxygen, and gas changes that make an unprotected vacuum exposure an emergency, then see how a spacesuit prevents them.

Follow delayed light from a galaxy through mirrors, detectors, deep exposures, multiple wavelengths, and redshift - and learn which conclusions are measurements and which depend on models.

See how pressure, layered protection, and human-centered testing let a spacesuit glove keep an astronaut’s hand safe and useful.

Read Scott's final expedition through its route, transport, weather, last diary pages, and the scientific records that outlasted the catastrophe.

Learn how Earth's rotation gives eastward launches a head start, and why orbit, latitude, and safety can outweigh that bonus.

Follow bone loss in microgravity, the exercise and nutrition countermeasures, and the evidence showing why recovery after landing takes time.

Use the Drake equation to separate what astronomy measures from what biology and technology still leave uncertain.

Track the Great Red Spot from a planet-sized storm to a shrinking, still-mysterious vortex—and see why scientists are testing the role of Jupiter's jet streams.

You are being told you cannot do astronomy without a great telescope. Chambers’s answer is a painter at an attic window, with two and a half inches of glass.

Bennett's 1903 handbook starts in a hammock: south slope, then soil, then glass. You learn shifting from repotting, and why a wet cover can kill what frost would spare.

Read the Kazakh Steppe as a living system of grass, seasonal water, migratory birds, mobile herding, Soviet agriculture, and spaceflight.

It is four o'clock. Two fiddles are already fighting in a saloon back of Chicago's Union Stock Yards. Upton Sinclair's 1906 novel starts as a wedding the plant will not pause for.

Snip the rim of a Sarsia and the bell goes still — while the thread you cut off keeps beating. An 1885 seaside physiology of animals with no brain.

You press the remote while the door is still. The button sends a coded radio request; it does not power the motor.

Plastic production starts before a plant ever sees a pellet: hydrocarbon feedstocks such as ethane, propane, and naphtha are converted into chemical building blocks. The first handoff is from feedstock to purified monomer, before polymeriza

No one would have believed that human affairs were being watched. The narrator is in Surrey, learning to ride a bicycle. In the telescope Mars is a pin-head of light. The Thing they have fired is already on the way.

Keep the reading frame fixed as you use an RNA codon chart to translate triplets into amino acids and recognize start and stop signals.

Kneel on the shingle and the stones stop looking empty. Henry Salt's 1922 book argues that botany starts here, not in the parterre.

Learn how a telescope turns light into evidence, from Galileo's first discoveries to the Moon, planets, stars, and nebulae you can begin to observe yourself.

In a New England schoolhouse a girl refuses a visiting-card. Du Bois's 1903 book starts there, then asks what it costs to see yourself through a nation that will not see you whole.

All children, except one, grow up. Wendy learns it at two, with a flower, when her mother wishes she could stay like this for ever. The 1911 novel does not start in Neverland.

Read Bertrand Russell?s guide to relativity through motion, light, clocks, space-time, gravity, evidence, and the limits of common sense.

Einstein opens beside a railway timetable, a clock, and a measuring rod: his book is for readers without advanced mathematics, but it asks for patience. He will rebuild space, time, distance, and simultaneity from operations an observer cou

Cups measure space; grams measure ingredients. Learn why a scale makes flour repeatable, tare turns one bowl into a workflow, and ratios let recipes travel.

A spacious drawing-room, a glass door, autumn trees, and several exits: Ibsen gives Hedda a beautiful room that already feels managed by someone else. After her honeymoon, her small acts of control—curtains, a maid’s hat, the story of the j

Gulliver Jones is a hungry, indebted navy lieutenant in a rainy New York slum, thinking about steak, tomatoes, and the promotion he believes he deserves—not Mars. When a dead stranger's carpet answers his frustrated wish, the novel launches

A child can turn a town into a private universe: for John Albee, Bellingham lives less on a map than in memory, where an elm, a river, vanished neighbors, and imagined places become larger than geography. The memoir asks what a place teache

Alice is bored beside her sister when a White Rabbit in a waistcoat runs past, watch in hand, crying that he is late. She follows him into a rabbit-hole where familiar rules—gravity, size, even identity—start to loosen.

Look at the first page. He does not start with a definition of anxiety. He starts with a hand that will not write, a walk that will not start, a meal that will not go down. You are in Vienna in 1926, holding a short book Freud finished the

Stand at the edge of a marsh and watch the tide thread through grass, mud, and open water. Which part would a young fish choose—and what would make that choice pay off?

Stand at the edge of a tidal creek: mudflat, marsh, open water, and roots meet within a few steps. Each offers different food, shelter, depth, and exposure. You are looking at a habitat mosaic, not one uniform wetland.

Stand at the edge of a marsh at low tide: quiet grass is cut by silver channels. Follow one channel inland and you find floodwater, fish, sediment, and community decisions moving through the same living system.

You are standing beside a tidal marsh: water fills the channels, yet roots may still be in drought stress. Salty water is harder for roots to use, and evaporation can concentrate salts between rain and tides. Surface water is only a clue; t

Nobody flies a Mars landing. On 18 February 2021 the room at JPL cheered eleven minutes after it was already over. Peak heating hits about 1,300 °C seventy-five seconds in. The parachute opens at 1,512 kph and is thrown away anyway. Four of

Nobody has seen a drop of Europa's ocean. The case for it rests on a wobble in a magnetic field, fractures that do not line up, and a thirty-fold difference in how far the surface should rise — and a spacecraft launched in 2024 is on its wa

The winning drawing had no buildable roof on it, and the state started pouring concrete anyway. What followed was six years of failed geometries, one sphere, 30,000 hand-written equations, 1,056,006 tiles — and an architect who walked out i

It opened to walkouts and dismissive reviews, and four days later its own director cut nineteen minutes out of it while it was still running in cinemas. Fifty-four years after that, 480 film directors voted it the greatest film ever made. Here is what Kubrick actually built, what he took out, and the one time he explained the ending.

Landing ropes hit the wet field at Lakehurst. Four minutes later the stern glowed. Follow the doped skin, the hydrogen leak, and the tests that separate a dramatic paint theory from the fire that actually ran.

The Moon retreats about 3.8 centimetres a year, and we know that because Apollo left mirrors on it and observatories have been firing lasers at them since 1970. But run that rate backwards and the Moon touches Earth 1.6 billion years ago —

In September 1859 the Sun threw a cloud of plasma at Earth, the aurora reached Panama, and telegraph operators found their keys working with the batteries disconnected. What happened, what Carrington himself refused to conclude, and why pow

A 420-tonne machine the length of a football field, bolted together in orbit one piece at a time. Follow the truss, the arrays and the radiators, the arm that walks itself end over end, the laboratories flown up by four space agencies — and

You are eight miles up when one engine goes quiet. The airplane does not fall — it is still flying at hundreds of knots, and that air is still pouring through a fan that fire is no longer driving. A restart is not a ground-start button. The

Follow the handoffs that let a Mars spacecraft brake, sense the ground, and place a rover safely without real-time help from Earth.

You sit down at the same desk, with the same document open, the same coffee going cold beside it — and for a few minutes nothing happens. It does not feel like resistance exactly. It feels more like the machinery has to be brought back up

See why an audience can sharpen a practiced response yet disrupt a difficult one—and learn what to notice when your own attention starts tracking the room.

Follow the Space Race from Sputnik’s first beep through Apollo 11, and ask whether a contest without a rulebook can have one clear winner.

You stand beside a ridge as the rising Moon looks enormous, then watch it shrink into open sky. A fixed camera finds nearly the same width in both places: the Moon illusion changes perception, not the Moon.

Look at the white UN truck on a Goma road. The letters on the door say MONUSCO, but people watching it remember an earlier name, and they will judge the truck by whether it arrives when shooting starts. On 30 November 1999, Security Council

Stand inside the Moon's moving shadow, distinguish partial, total, and annular views, then meet the hidden corona and learn to watch safely.

Compare four wartime addresses by their audiences, legal acts, evidence, and consequences—not by the myth that one speech starts a war.

You float through a hatch at the end of the workday and close the door on a cabin roughly the size of a phone booth. There is no bed. Astronaut Samantha Cristoforetti slips into a sleeping bag attached to the wall of her International Space

You are watching a rover at a Martian rock field. By the time a signal returns, a hazard may already be under its wheels, so people plan sequences while the rover handles nearby motion.

Trace James Croll's nineteenth-century battle between a short solar clock and the deep time recorded by rocks, then compare his Impact Theory with modern star formation and fusion.

Two empty lots in Bedford-Stuyvesant, eight weeks in the summer of 1988, and one of the loudest arguments American film has ever started. What Spike Lee actually built on that block, and why the question the movie asks still gets a different answer depending on who you ask.

You stand in a marsh that looks like a wall and learn it is a sieve. Follow waves, surge, storage, roots, and the measurements that keep a flood claim honest.

When the pantry fails, replace the ingredient's job: match the acid, water, fat, protein or starch, then keep tested food-safety controls intact.

A custard thickens in a band only a few degrees wide. Past that band the same proteins make breakfast.

Miso, soy and koji: the mould that built East Asian flavour. Koji opens starch and protein, then salt-tolerant microbes turn that preparation into a family of savoury foods.

A gravy stays thin until starch granules drink, swell and fall apart. Roux and slurry are two ways in.

A jar of flour and water is not a recipe. It is a habitat that elects its own government, then taxes every loaf you bake.

An Andean tuber fed a continent, then failed catastrophically. The biology and history behind the humble potato.

Learn how migrating birds combine an inherited direction, the Sun and stars, Earth's magnetic field, landmarks, smells, weather, and memory to find routes and stopover places.

Follow the Moon’s differential gravity from ocean bulges to local tide tables, and see how the Sun and coastlines reshape the pattern.

Understand why astronauts float: Earth’s gravity still acts in orbit, but the spacecraft, crew, and loose objects are all falling around the planet together.

Follow the Saturn V from its five-engine first stage and three-stage architecture through Apollo 11’s launch, translunar injection, lunar landing, and safe return.

Follow groundwater through limestone, compare cave types, and see how lava tubes, collapse, and mineral deposits shape underground spaces.

Learn how spectroscopy reads atomic fingerprints in starlight to reveal elements, temperature, motion, and stellar history.

Explain why sound needs matter, how spacecraft materials can carry vibration, and why radio communication crosses the vacuum as electromagnetic energy.

Learn how moving layers of Earth's atmosphere bend and redistribute starlight, why planets usually look steadier, and how astronomers correct the shimmer.

See how food, sleep, hygiene, toilets, water recycling, and airflow make ordinary life possible aboard an orbiting spacecraft.
