The James Webb Space Telescope has provided the first close-up look at WD 1856 b, a Jupiter-sized planet orbiting a white dwarf. The planet's unusual orbit and high temperature suggest it survived its star's death through gravitational interactions, challenging existing models of stellar evolution.
A new study suggests that some of the coldest objects in the Milky Way, currently classified as stars, might be alien megastructures. Astrophysicist Amirnezam Amiri proposes these could be Dyson swarms, engineered systems harvesting stellar energy and releasing infrared heat, offering a new method to detect them.
Lego is releasing a new 1,252-piece Lego Icons set that allows fans to build their own replica of the Hubble Space Telescope. The set, available August 1 for $140, features detailed interior components and an astronaut minifigure.
NASA released new, highly detailed images of the Centaurus A galaxy captured by the James Webb Space Telescope. These images, taken with the MIRI and NIRCam instruments, reveal intricate dust structures and star formation, offering scientists new data to study galactic evolution.
Scientists using the James Webb Space Telescope have detected gases, including dimethyl sulfide (DMS), on exoplanet K2-18b that are linked to biological activity on Earth. While the signal is strong, it's not yet confirmed as life, with researchers awaiting further data to rule out non-biological explanations.
ESA's Euclid telescope has identified two of the most ancient quasars, dating back to when the universe was only 670 million years old. This discovery significantly increases the number of known ancient quasars, offering new insights into the early universe.
Astronomers using Hubble and James Webb telescopes found light from MXDFz4.4, a tiny galaxy from the early universe. This galaxy, existing shortly after the Epoch of Reionization, shows powerful ultraviolet light escaping, offering a rare glimpse into cosmic transformation.
NASA has launched a $30 million robotic mission, the Link spacecraft, to rescue its aging Swift Observatory from burning up in Earth's atmosphere. Built by Katalyst Space Technologies and launched by Northrop Grumman, the mission aims to capture and re-orbit the telescope, potentially extending its life and setting a precedent for satellite servicing.
A mission to rescue NASA's aging Swift Observatory, which is sinking towards Earth due to solar storms, has been launched. A three-armed spacecraft named Link, developed by Katalyst Space Technologies, will attempt to capture and boost the telescope's orbit.
NASA has launched a $30 million robotic mission to rescue the aging Swift space telescope, which is falling towards Earth. The unprecedented operation, if successful, could enable other satellites to be given a second life. The robot was launched Friday from the Pacific Ocean.
A Nasa-funded spacecraft, LINK, has been launched to rescue the Swift observatory, a telescope at risk of crashing to Earth due to increased solar activity. The mission, developed by Katalyst Space Technologies, involves a robotic craft attempting to grab and re-orbit the telescope, a high-risk operation never before attempted.
NASA plans an unprecedented mission to boost its aging Swift Observatory back into orbit using a robotic spacecraft named LINK, launched from an airplane. The $30m mission aims to extend Swift's scientific operations beyond 2030, saving significant costs compared to building a new telescope.
NASA is launching an emergency mission to boost the orbit of its 20-year-old Neil Gehrels Swift Observatory, which is falling out of orbit. The mission, costing $30 million, involves a robotic spacecraft named LINK launched from an airplane via a Pegasus XL rocket, aiming to save the telescope for continued scientific research.
The ESA's Euclid space telescope has captured the largest and most detailed visible-light image of the Milky Way's galactic bulge, containing over 60 million stars, to aid in exoplanet detection and mass measurement via microlensing.
NASA's TESS satellite has identified two exoplanets, TOI-791 b and TOI-791 c, described as the "puffiest" ever found, with densities similar to cotton candy despite their Jupiter-like size. Discovered in the same star system, these rare finds offer new insights into planetary formation.
歐洲太空總署的歐幾里得望遠鏡捕捉到銀河系中心區迄今最大、最細緻的可見光影像，呈現6000萬顆恆星，有助於天文學家利用微重力透鏡現象，將已知系外行星數量從約6000顆增至超過10萬顆。
The European Space Agency's Euclid telescope captured a bright image of the Milky Way's galactic bulge, providing crucial context for NASA's upcoming Nancy Grace Roman Space Telescope mission, which will chart stellar changes and identify cosmic objects.
Nasa is launching a robotic rescue mission with Arizona-based Katalyst Space to save its Neil Gehrels Swift Observatory, which is rapidly losing altitude due to increased solar activity. The LINK spacecraft will attempt to dock with and raise Swift's orbit, potentially extending its life by a decade.
NASA's Nancy Grace Roman Space Telescope has arrived at Kennedy Space Center, Florida, for final preparations before its launch on a SpaceX Falcon Heavy rocket. Targeting an August 30, 2026 launch, the $4.3 billion observatory will investigate dark energy, dark matter, and search for exoplanets.
NASA's Swift Boost mission, launching June 27, aims to rescue the Neil Gehrels Swift Observatory by using a robotic spacecraft named LINK to boost its orbit. The observatory's orbit is decaying faster than expected due to increased solar activity.
Astronomers using the James Webb Space Telescope have confirmed that Terzan 5, located in the Milky Way's bulge, is not a globular star cluster but a 'bulge fossil fragment.' It has undergone at least four distinct star formation phases, offering new insights into galactic history.
Pesquisa liderada pela USP encontrou uma nova forma de identificar estrelas que engoliram planetas: a análise da abundância de berílio. A estrela HD 129171 apresentou maior quantidade desse elemento, indicando a ingestão de material rochoso.
