The current process for planetary protection policy development is inadequate to respond to increasingly complex solar system exploration missions, says a new report from the National Academies of Sciences, Engineering, and Medicine.

To answer significant questions about planetary systems, such as whether our solar system is a rare phenomenon or if life exists on planets other than Earth, NASA should lead a large direct imaging mission – an advanced space telescope – capable of studying Earth-like exoplanets orbiting stars similar to the sun, says a new congressionally mandated report by the National Academies of Sciences, Engineering, and Medicine.

April’s evening skies offer plenty of stars to check out. However, aside from Jupiter low in the west, planets are in short supply. Our latest Sky Tour podcast helps you track down Mars, Saturn, and much during April’s pleasant nights.

Knowing that you've found signs of life beyond Earth may not be as clear-cut and simple as one might think.

NASA scientists used a neural network called ExoMiner to examine data from Kepler, increasing the total tally of confirmed exoplanets in the universe.

The answer has everything to do with falling flat on your face

NASA's Roman Space Telescope has successfully integrated the Roman Coronagraph, a vital step in detecting planets far beyond our solar system. This tool will help block starlight, enabling the telescope to capture faint planetary light. The coronagraph marks a significant advancement in exoplanet detection, allowing the telescope to observe planets 100 million times fainter than their stars. The mission will provide insights into dark energy, exoplanets, and more, paving the way for future observatories like the Habitable Worlds Observatory.

In an experiment simulating what happens deep in the interiors of planets, scientists have found that liquid can be compressed into ice crystals – even at extremely high temperatures

Scientists know that two-star systems can support planets, but the question has remained whether an Earth-size terrestrial planet were orbiting two suns could it support life. A study in the journal Nature Communications has now found that an Earth-like planet orbiting two stars could be habitable if it were within a certain range from its two stars.

New observations by the Smithsonian’s Submillimeter Array, a radio telescope atop Mauna Kea in Hawaii, are shedding light on planet formation. The array provides sharp views by combining eight antennas into the equivalent of a single, large telescope. It can resolve details as small as a dime seen from seven miles away.

Koenig and his colleagues examined an area of space called W5, which lies about 6,500 light-years away toward the constellation Cassiopeia—about 6 trillion miles. Their research indicates the prospects for hypothetical alien life there are disappointing.

Seven years ago, astronomers boggled when they found the first runaway star flying out of our Galaxy at a speed of 1.5 million miles per hour. Theorists wondered: Could the same thing happen to planets? New research shows that the answer is yes.

A team of Carnegie scientists has discovered three giant planets in a binary star system composed of stellar ''twins'' that are also effectively siblings of our Sun. One star hosts two planets and the other hosts the third. The system represents the smallest-separation binary in which both stars host planets that has ever been observed. The findings, which may help explain the influence that giant planets like Jupiter have over a solar system's architecture, have been accepted for publication in The Astronomical Journal.
