64 doors into real science at its most unsettling. Ordered by publication date. Each one begins with an observation and leads to the full illustrated story.

Laika: When Care Could Not Bring Her Home

Laika: When Care Could Not Bring Her Home

Before a spacecraft without a return system carried Laika into orbit, one of the doctors brought her home. Her story asks what care means when the people offering comfort also accept the decision that places a life beyond their help.

One Explosion, Several Arrivals

A foreground cluster can send the light of one supernova toward Earth along several routes. Comparing their arrival times turns a repeated appearance into a test of the lens and cosmic distances.

The Moon’s Valuable Shadows
07 / Lunar south pole / evidence and access

The Moon’s Valuable Shadows

Sunlit ridges and deeply shadowed crater floors make the lunar south pole scientifically valuable and operationally difficult. Evidence for ice is a starting point, rather than a proven inventory of usable fuel.

An Ocean Crust Holding an Older Galactic Clock

Traces of plutonium-244 in Pacific crust carry a record of heavy-element production beyond Earth. Missing curium helps constrain when that production occurred, but the oldest headline estimate depends on how the crust incorporated the elements.

Which World Is Producing the Radio Bursts?

Which World Is Producing the Radio Bursts?

A submitted study attributes highly polarized radio bursts to Beta Pictoris b. The planet is already known, but identifying the source of its reported radio emission requires localization, interference checks and a physical model.

What Is Hidden Inside the Little Red Dots?

Some compact red sources discovered by Webb may contain rapidly accreting black holes inside dense gas. The evidence comes from spectra and competing physical models, while the population may still contain more than one kind of object.

The Cold Giant That Exposed a Cloud Problem

Webb’s measurements of Epsilon Indi Ab do not match a simple cloud-free atmosphere. Water-ice clouds are a favored explanation for the planet’s infrared behavior, showing how an unseen atmosphere can complicate a measured spectrum.

Where Was the Sun Born?

Where Was the Sun Born?

Stars that resemble the Sun carry chemical and age clues to the Milky Way's past. Their pattern supports a migration story, but it cannot draw the Sun's exact route through the galaxy.

27 / An orbiter beyond its deadline

Juno's Second Life at Jupiter

The orbiter reached Jupiter in 2016 to look beneath its clouds. Years beyond its original science plan, it is still returning measurements of a planet and moons that refuse simple descriptions.

06 Uncertainty and limits

Keep the boundary of the claim in view.

Field Notes connect an illustrated article with a focused scientific question. Read the measurements, assumptions, and unresolved points together. The strongest takeaway is often a clearer statement of what we know and exactly what remains to be tested.

Ask yourself How large are the uncertainties, and which claim would go beyond the data?
