No isotope of technetium has a half-life longer than NUMBER@1 million years -LRB- 98Tc -RRB- , so its detection in red giants in NUMBER@2 helped bolster the theory that stars can produce heavier elements .

No isotope of technetium has a half-life longer than NUMBER@1 million years -LRB- 98Tc -RRB- . This means that its detection in red giants in NUMBER@2 helped support the theory that stars can produce heavier elements .
