Thanks to data from a magnified, multiply imaged supernova, a team of researchers has successfully used a first-of-its-kind technique based on the Refsdal method to measure the expansion rate of the Universe. Their data provide insight into a longstanding debate in the field and could help scientists more accurately determine the Universe’s age and better […]
HIP 99770 b is the first exoplanet detected through a pioneering approach that combines direct imaging with astrometry, the precise measurements of a star’s motion in the sky. This innovative method holds great promise for enhancing the efficiency of exoplanet searches, bringing us closer to the long-awaited discovery of an Earth-like twin in the vast […]
In 2019, the Event Horizon Telescope (EHT) collaboration produced the first-ever image of a black hole, stunning the world. Now, scientists are taking it further. The next generation Event Horizon Telescope (ngEHT) collaboration aims to create high-quality videos of black holes. But this next-generation collaboration is groundbreaking in other ways, too. It’s the first large […]
When you collect vast amounts of data, most of them will likely be irrelevant or uninteresting. But, hidden in all that noise, you may find a jewel. The data where one scientific jewel, a supernova, has just been found is the collection of observations by the Hubble Frontier Fields (HFF) project. HFF drew on the […]

Are we alone in the universe? This is a question that has intrigued humans for centuries and inspired countless studies and works of fiction. But are we getting closer to finding this out? Now that the James Webb Space Telescope (JWST) is in operation, we might have taken one giant leap in being able to […]

An Earth-like planet named GJ 1252b orbiting an M dwarf — the most common type of star in the universe — appears to have no atmosphere at all. This discovery could cause a major shift in the search for life on other planets. Because M-dwarfs are so ubiquitous, this discovery means a large number of […]
Blasting out Earth’s location with the hope of reaching aliens is a controversial idea – two teams of scientists are doing it anyway If a person is lost in the wilderness, they have two options. They can search for civilization, or they could make themselves easy to spot by building a fire or writing HELP […]
Pluto, the Solar System’s largest dwarf planet, just became even more interesting with a report that icy lava flows have recently covered substantial tracts of its surface. In this context, “recently” means probably no more than a billion years ago. That’s old, of course – and there is no suggestion that volcanoes are still active […]
When the most massive stars die, they collapse to form some of the densest objects known in the Universe: black holes. They are the “darkest” objects in the cosmos, as not even light can escape their incredibly strong gravity. Because of this, it’s impossible to directly image black holes, making them mysterious and quite perplexing […]
The James Webb Space Telescope is scheduled to head to space on Dec. 18, 2021. With it, astronomers hope to find the first galaxies to form in the universe, will search for Earthlike atmospheres around other planets and accomplish many other scientific goals. I am an astronomer and the principal investigator for the Near Infrared […]
