Pulsar Glitches Probe a Star’s Hidden Rotation Why the Effective Number of Neutrinos Need Not Be an Integer Measuring Uranus’s Internal Heat Takes More Than a Snapshot How Mission Teams Choose What a Spacecraft Points at Next A Pulsar Spends Its Spin to Power Its Surroundings Fast-Moving Neutrinos Slow the Growth of Cosmic Structure Why ‘Ice Giant’ Doesn’t Mean a Frozen Planet Water Masers Turn Galactic Gas Into a Radio Amplifier A Spacecraft Can Distort the Magnetic Field It Tries to Measure Estimate a Variable Star’s Brightness With Comparison Stars Janus and Epimetheus Swap Orbits Without Colliding A Gravitational Lens Can Bring One Distant Star Into View Spin Stabilization Changes How a Spacecraft Sees Space Red Stars Can Trick the Eye During Brightness Estimates Galileo’s Cracked Lens and Its Seventeenth-Century Frame The Chemistry That Keeps a Meteor Train Glowing Could a Virus Be Evidence of Life Beyond Earth? What to Record When a Variable Star Is Too Faint to See Galileo’s Micrometer Used Two Eyes to Measure Moon Positions A Meteor’s Color Is a Poor Chemical Fingerprint Mars Radiation Can Erase Amino Acids Before a Rover Finds Them After a Course Correction, Spacecraft Navigators Measure Again A Nova Can Erupt Again Because Its White Dwarf Survives Adiabatic vs. Isocurvature: Two Ways to Describe Cosmic Seeds Heating Martian Soil Can Change the Organics a Rover Detects Optical Navigation Turns Spacecraft Images Into Trajectory Clues The Disk Instability Behind a Dwarf Nova’s Outburst E Modes and B Modes: Reading the CMB’s Polarization Ganymede’s Magnetosphere Lives Inside Jupiter’s Lensed Quasars: One Source, Several Arrival Times High-Gain and Low-Gain Antennas Make a Pointing Trade-Off Galactic Dust Complicates the Search for Primordial B Modes Home
