The vast majority of planets near foreign stars are discovered by astronomers with the help of sophisticated methods. An exoplanet like Beta Pictoris c does not appear in the image, but reveals itself indirectly in the spectrum. A team of scientists from the Max Planck Institutes for Astronomy and Extraterrestrial Physics has now succeeded in ...
When you look up at the night sky at the galaxies, how do you know whether the specks of light that you see are bright and far away, or relatively faint and close by? One way to find out is to compare how much light the object actually emits to how bright it appears. The ...
An international team of researchers has found that some of the oldest terrain on Venus, known as tesserae, has layering that seems consistent with volcanic activity. The finding could provide insights into the enigmatic planet’s geological history. Tesserae are tectonically deformed regions on the surface of Venus that are often more elevated than the surrounding ...
Astronomers using the National Science Foundation’s Very Long Baseline Array (VLBA) have made the first direct geometric measurement of the distance to a magnetar within our Milky Way Galaxy — a measurement that could help determine if they are the sources of the long-mysterious Fast Radio Bursts (FRBs). Magnetars are a variety of neutron stars ...
When stars like our Sun die, all that remains is an exposed core — a white dwarf. A planet orbiting a white dwarf presents a promising opportunity to determine if life can survive the death of its star, according to Cornell researchers. In a study published in the Astrophysical Journal Letters, they show how NASA’s ...
New composite images made by NASA’s Cassini spacecraft are the most detailed global infrared views ever produced of Saturn’s moon Enceladus. And data used to build those images provides strong evidence that the northern hemisphere of the moon has been resurfaced with ice from its interior. Cassini’s Visible and Infrared Mapping Spectrometer (VIMS) collected light ...
Jupiter, named for the king of the ancient Roman gods, commands its own mini-version of our solar system of circling satellites; their movements convinced Galileo Galilei that Earth is not the center of the universe in the early 17th century. More than 400 years later, astronomers will use NASA’s James Webb Space Telescope to observe these ...
Our solar system has one habitable planet — Earth. A new study shows other stars could have as many as seven Earth-like exoplanets in the absence of a gas giant like Jupiter. This is the conclusion of a study led by UC Riverside astrobiologist Stephen Kane published in The Astronomical Journal. The search for life in outer ...
Lithium is becoming common in our everyday lives. It is the key ingredient in the batteries of our mobile phones and electric vehicles, but have you ever wondered where it comes from? A new study that was published in Nature Astronomy and was led by Prof. ZHAO Gang and Dr. Yerra Bharat Kumar from the ...
Over the course of 182 days, the eROSITA X-ray telescope has completed its first full sweep of the sky that it embarked upon about a year ago. This new map of the hot, energetic universe contains more than 1 million objects, roughly doubling the number of known X-ray sources discovered over the 60-year history of ...
