Chris Jeremia is a writer at Space Daily covering space, science, and Mind & Meaning. She holds a degree in communications and teaches yoga alongside her writing, which shows up in how readily she covers the mind under pressure as well as launches and telescopes. Her pieces start from primary sources: agency releases, observatory data, and the journal papers behind the headlines. She is direct about what a single study can and cannot show.

Metal detector finds Finland's largest Iron Age coin hoard near church

Kalle Lappinen had written the first signal off as buried ore. He went back to it, and there were coins there too. The museum’s own announcement came with the qualifiers already attached: the coins have not been cleaned, separated or counted, and the exact weight, the number and the more precise dating all wait on further study. A second statement ten days later added a limit on the word Viking.

Trillion-mile gas stream aligns with triple star's rings, defying chance

A team working with ALMA puts the odds of that alignment arising by chance at about 0.07 percent, and reads it as evidence that the incoming gas is what set the outer ring's angle. The paper's own accounting complicates that: the stream's total angular momentum is well short of the disk's, and on the narrower measure of angular momentum per unit mass the paper says the two are within error bars of each other.

In the first half of the 19th century BCE a woman named Anna-anna went back and…

The letter is catalogued as Kt 94/k 1150, one of several hundred contract and letter envelopes found still sealed at Kanesh, the Anatolian town that housed an Assyrian merchant colony. The scanner that made it readable was built to be carried, because museums do not usually let their tablets leave the building and the two commercial machines the paper names weigh almost two tonnes and up to six and a half. It comes apart into eight pieces.

Saturn's solar wind funnel peaks at a different hour than Earth's does

Earth's magnetospheric cusp, the funnel that lets solar wind particles down toward the atmosphere, peaks close to local noon. A survey of Cassini magnetometer and plasma data found 67 crossings at Saturn, and once the count was normalised by how long the spacecraft spent at high latitude, the occurrence rate peaked at 13 to 15 local time. Three crossings sat near 20 local time, somewhere Earth's cusp is hardly ever seen.

Invasive Joro spiders eat different prey than native orb weavers, but don't seem to harm them

The gut contents of 356 female orb weavers, collected in a single October and sequenced family by family, put the introduced spider's prey list statistically distinct in composition from its neighbours' while overlapping them on many prey families, and wider on a count the authors say likely reflects how many of each spider were caught. Native gut contents at Joro-occupied sites were not distinguishable from those at sites with no Joros.
