Lonely Giants: Rogue Planets in a Dark World

By Muaz Reza ’27 When we think of planets in the solar system, one vivid image comes to mind: multicolored spheres arranged in neat circular orbits around one flaming sun. However, many other planets occupy a less conventional reality. Within our universe are worlds – named ‘rogue planets’ – untethered to stars. They drift alone in the darkness, with no sunset or sunrise to illuminate their horizons, and their existence and origins stretch our current understanding of all celestial objects. A rogue planet, as NASA explains, is any body that is not gravitationally bound to a star. Some of these objects may have once belonged to a solar system, but were subsequently ejected through one of a variety of methods. For example, early phases of solar system formation can be turbulent enough ...

Your Mind is the Map: What Polynesian Wayfinding Teaches Us About Knowledge in the Age of GPS

April 22, 2025 By: Rakhi Jain ’26 Imagine you’re stranded on a deserted road at night, your phone battery drained and GPS useless. That familiar panic sets in; you’re lost. Now amplify this feeling a thousandfold: you’re sailing the vast Pacific Ocean, hundreds of miles from land, surrounded only by endless horizons of water. No electronics, no maps, just stars, waves, and intuition. Could you navigate your way home? Fifty years ago, this scenario wasn’t hypothetical. It was the extraordinary reality faced by the crew aboard the traditional Polynesian sailing canoe Hōkūleʻa during their legendary 1976 voyage from Hawaiʻi to Tahiti, spanning over 2,500 nautical miles. They succeeded using just ancient Polynesian navigation methods. Revisiting the story of Hōkūleʻa today invites us ...

Assessing Quantum Interferometry to Enhance Telescopic Efficiency: A PHY440 (Astronomy) Research Project

By Rania Ali-Svedsäter '26 In modern astronomy, quantum communications systems have proven to ascertain numerous benefits for increased telescopic efficiency. Modern prototypes pair standard interferometry with various quantum communication networks, which accumulate to operate a “quantum telescope.” Generally, quantum communications systems can aid information processing between telescopes, increasing the overall scalability of the telescope. The scalability refers to the telescope’s ability to extract more light than made possible from standard interferometry, enabling telescopes to produce high-resolution images from greater distances. Enhanced scalability contributes to the overall efficiency of a telescope, indicating crucial development for higher resolution imagery within modern ...

Dark Stars: Keys to Unlocking the Secrets of the Universe?

By Cyrus Law '27 Despite only orbiting the sun for 2 years, the James Webb Space Telescope (JWST) has captured a plethora of high-quality images that the previous Hubble Telescope failed to. In December of 2022, the JWST identified four galaxies (JADES-GS-z10-0, JADES-GS-z11-0, JADES-GS-z12-0, and JADES-GS-z13-0) high in redshift, indicating that these galaxies are extremely distant and therefore old. However, a closer look suggests that the latter 3 of these 4 galaxies may be supermassive versions of the theoretical dark stars. The concept of dark stars was first proposed by a team of university professors from New York and Texas in 2007. These dark stars are thought to have existed early in the universe and are possibly the first stars created. Even though both dark stars and regul...
