The periodic table organizes all the known elements by atomic number, which is the number of protons in each atom of the element. This version of the table, which draws on data compiled by astronomer Jennifer Johnson from Ohio State University, shows our current understanding of how each element found on Earth was originally produced. Most of them ultimately have cosmic origins. Some elements were created with the birth of the universe, while others were made during the lives or deaths of stars. The Nancy Grace Roman Space Telescope will help us understand the cosmic era when stars first began forming. The mission will help scientists learn more about how elements were created and distributed throughout galaxies.

The National UFO Historical Records Center is a 501(c)(3) Nonprofit Corporation in the state of New Mexico that seeks to educate the public on the history of the UFO/UAP phenomenon, preserve and digitize historical documents and media, and promote scientific research into the topic. We are an organization of leading researchers and archivists who together hold the largest collection of historical UFO records in the United States of America. We intend to bring all these collections together under one roof to preserve this important piece of history for future generations. There is no central place for the public to get the true story of UFOs and we endeavor to provide clarity to current developments and past events through the lens of historical records and data.
When and where can you see the northern and southern lights also known as the aurora? This page provides a prediction of the aurora’s visibility tonight and tomorrow night in the charts below. The animations further down show what the aurora’s been up to over the last 24 hours and estimates what the next 30 minutes will be like. The aurora’s colorful green, red, and purple light shifts gently and often changes shape like softly blowing curtains.
The SuperNova Early Warning System (SNEWS) is a global network of neutrino experiments sensitive to supernova neutrinos. The goal of SNEWS is to provide the astronomical community with a prompt alert of an imminent Galactic core-collapse event. This will allow for complete multi-messenger observations of the supernova across the electromagnetic spectrum, in gravitational waves, and in neutrinos.
The observation of a neutrino burst can thus provide a warning for astronomers that the opportunity to get a rare glimpse at the collapse of a star, resulting in a supernova, may soon be presenting itself. In addition, there is a real chance that a Galactic supernova may be observable with the naked eye, making this alert interesting to hobby astronomers and the general public alike. Most large-scale neutrino detectors around the globe thus joined forces in the SNEWS network to provide a high-sensitivity alert to interested parties. In addition, gravitational wave detectors like LIGO and Virgo have sensitivity to asymmetrically-collapsing supernovae and can both benefit from and contribute to such an alert.
The early supernova alert project has a central computer which accepts neutrino burst candidate messages from neutrino detectors around the world and sends an alert to astronomers if it finds a coincidence within a few seconds.

LibreTexts is the adaptable, user-friendly open education resource platform that educators trust for creating, customizing, and sharing accessible, interactive textbooks, adaptive homework, and ancillary materials. We collaborate with individuals and organizations to champion open education initiatives, support institutional publishing programs, drive curriculum development projects, and more.
LibreTexts is the largest centralized open education project and platform online. Founded in 2008 at the University of California, Davis as the ChemWiki, the LibreTexts mission is to unite students, faculty and scholars in a cooperative effort to develop an easy-to-use online platform for the construction, customization, and dissemination of open educational resources (OER) to reduce the burdens of unreasonable textbook costs to our students and society.
The EHT is an international collaboration that has formed to continue the steady long-term progress on improving the capability of Very Long Baseline Interferometry (VLBI) at short wavelengths in pursuit of this goal. This technique of linking radio dishes across the globe to create an Earth-sized interferometer, has been used to measure the size of the emission regions of the two supermassive black holes with the largest apparent event horizons: SgrA* at the center of the Milky Way and M87 in the center of the Virgo A galaxy. In both cases, the sizes match that of the predicted silhouette caused by the extreme lensing of light by the black hole. Addition of key millimeter and submillimeter wavelength facilities at high altitude sites has now opened the possibility of imaging such features and sensing the dynamic evolution of black hole accretion. The EHT project includes theoretical and simulation studies that are framing questions rooted at the black hole boundary that may soon be answered through observations.
By linking together existing telescopes using novel systems, the EHT leverages considerable global investment to create a fundamentally new instrument with angular resolving power that is the highest possible from the surface of the Earth. Over the coming years, the international EHT team will mount observing campaigns of increasing resolving power and sensitivity, aiming to bring black holes into focus.
What is known? What isn’t known? Knowable Magazine, the digital publication from Annual Reviews, seeks to make that knowledge accessible to all. Knowable Magazine explores the real-world significance of scholarly work through a journalistic lens. We report on the current state of play across a wide variety of fields — from agriculture to high-energy physics; biochemistry to water security; the origins of the universe to psychology.
Knowable Magazine content is thoroughly researched, reported, edited, copy-edited and fact-checked. Review articles in Annual Review journals provide ideas, but editorial decisions and reporting decisions are made by the magazine staff, guided by what will best inform and intrigue readers. In this task they are guided by a Magazine Advisory Group, which includes leading journalists and communicators working in a variety of media.
OpenWetWare is an effort to promote the sharing of information, know-how, and wisdom among researchers and groups who are working in biology & biological engineering.

The U.S. Drought Monitor (USDM) is a map released every Thursday, showing where drought is and how bad it is across the U.S. and its territories. The map uses six classifications: normal conditions, abnormally dry (D0), showing areas that may be going into or are coming out of drought, and four levels of drought: moderate (D1), severe (D2), extreme (D3) and exceptional (D4).
The data cutoff for Drought Monitor maps is each Tuesday at 8 a.m. EDT. The maps, which are based on analysis of the data, are released each Thursday at 8:30 a.m. Eastern Time.

The U.S. Drought Monitor has been a team effort since its inception in 1999, produced jointly by the National Drought Mitigation Center at the University of Nebraska-Lincoln, the National Oceanic and Atmospheric Administration and the U.S. Department of Agriculture. Meteorologists and climatologists from the NDMC, NOAA and USDA take turns as the lead author of the map, usually two weeks a time. The author’s job is to do something that a computer can’t. When the data is pointing in different directions, they make sense out of it.
