Rohini Devasher My recent visit to Berlin for a planetary science conference coincided with Berlin Art Week. The exhibitions were mostly light years away from space and planets, but, to my surprise, some were scientific. Take Rohini Devasher’s exhibition Borrowed Light, an intriguing exploration of astronomy. Its centrepiece, One Hundred Thousand Suns (pictured above), was…

The James Webb Space Telescope (JWST) has discovered yet another troubling sign that there’s something very wrong with our model of the universe. Depending on which part of the universe astronomers measure, the cosmos seems to be growing at different rates — a problem scientists call the Hubble tension. Measurements taken from the distant, early…

Any day now, our night sky will host a guest star. Stargazers and astronomers around the world continue to gaze toward the Corona Borealis constellation 3,000 light-years from Earth, where a long-dead star is expected to reignite in an explosion so powerful it will briefly rival the brilliance of Polaris, the North Star. The stellar…

In about 11 years, one of humankind’s most ambitious missions is set to launch into space. Decades in the making, the Laser Interferometer Space Antenna, or LISA, could revolutionize our understanding of the universe through its detections of gravitational waves. This is your in-the-weeds walkthrough of the science that will make this intrepid project possible.…

The latest generation of SpaceX’s Starlink satellites are leaking even more potentially disruptive radiation into low-Earth orbit than their predecessors, a new study shows. Researchers warn that the continuing unchecked deployment of the spacecraft could lead to an irreversible “inflection point,” beyond which we can no longer properly study the universe’s most exciting objects. In…

The James Webb Space Telescope (JWST) has found a bizarre galaxy in the early universe whose gas outshines its stars, marking  it out as a possible missing link in galactic evolution. The galaxy, called GS-NDG-9422 (9422), was spotted just one billion years after the Big Bang and is filled with massive stars burning nearly twice…

Astronomers have discovered a distant planet that has offered them a rare glimpse of what our planet may look like 8 billion years in the future. The planet, called KMT-2020-BLG-0414 and located 4,000 light-years from Earth, is a rocky world orbiting a white dwarf — the embering husk of a star. Our sun is expected…
