A candidate for an Earth-sized exoplanet with a year's orbit – but a frozen world

  • No comments
A possible rocky planet, about 6% larger than Earth, appears to complete an orbit in about 355 days and receives only about 29% of the star's radiation that Earth receives - putting it on the verge of the "habitable zone"

Webb captures the “final breath” of a sun-like star in the Helix Nebula

  • No comments
The sharpest infrared observation yet of a nearby planetary nebula reveals comet-like bonds of gas and dust, illustrating how material from a dying star becomes the seeds of future systems.

New simulations offer a solution: This is how black holes grew quickly to become supermassive in the early universe

  • No comments
Simulation study claims that the young universe was chaotic and rich in dense gas, allowing even “light seeds” to undergo “binge” episodes that exceeded conventional growth limits

The telescope will simultaneously measure visible and infrared light to separate “noise” from the host star from the signature of the atmosphere, and will help improve observations by the James Webb Space Telescope.

ALMA measurement and the Sonyaev-Zeldovich effect indicate “overheating” about 1.4 billion years after the Big Bang, challenging models of galaxy cluster formation

Pulsar's twinkle reveals the hidden fabric of space

  • No comments
SETI Institute observations of the Allen Telescope Array over about 10 months have shown how the twinkling of pulsars varies over time, creating tiny delays that require correction in precise timing measurements. The subtle twinkling of a pulsar reveals

Mysterious object challenges simple models of dark matter

  • No comments
An unusual observational case: an object with a mass of a million solar masses, which has no clear “parallel” among known objects, may be the result of a collision between different types of dark matter

Why do solar flares “pulse” at a constant rate?

The eye is immediately drawn, in this month’s new image from the James Webb Space Telescope (NASA/ESA/CSA), to the “monster” at the center: the galaxy cluster Abell S1063. This huge collection of galaxies, located about 4.5 billion light-years from Earth in the constellation Grus (the Crane), dominates the field of view. A closer look reveals glowing streaks and curved arcs around it—the product of gravitational lensing—and it is precisely these that attract the researchers’ attention: these arcs are magnified and distorted images of faint, ancient galaxies from the distant universe.

What if dark energy doesn't exist? New theory could rewrite the expansion of the universe

Researchers suggest that the accelerating expansion of the universe could be due to the geometry of space-time and the extension of the theory of gravity – without adding a “mysterious element” to the equations to match observations
